TCS Antibody Purification Kit (ab109207)

Submit a review Q&A (7)

Overview

  • Product name

    TCS Antibody Purification Kit
    See all Antibody Purification kits

  • Product overview

    TCS Antibody Purification Kit (ab109207) has been designed for tissue culture supernatant purification, and can be used to purify 10-50 mL in each purification. Each column can purify up to 5 mg of antibody.


    This kit works by coupling highly purified protein A to agarose beads and can therefore be used to purify IgG fractions from hybridoma supernatants. The antibody is captured on the TCS resin and unwanted substances are removed by a simple wash procedure. The purified product is then eluted and neutralized.


    The antibodies purified with the TCS Antibody Purification Kit are fully compatible with our Lightnign-Link® Antibody Conjugation kits and our Oligonucleotide Conjugation Kit. To purify antibodies from TCS for use with our nanoparticle conjugation kits, please use our TCS Antibody Purification Kit - Nanoparticles (ab270554).


    ab109207 is not suitable for goat antibody purification.

Question

Hi:

I would like to have advice for the selection of a antibody purification kit. I have a commercial antibody which contains both sodium azide and BSA and I need to get ride of both of them for an application. There are mutiple kits listed on your web site (cat # ab102783, ab102784,ab109207) for this purpose. However, I am not really familiar with the products and pro/con of them.

Following is the techinical info for our antibody, and I would really appreciate your help to suggest the right kit for me.

Size 100 ul
Class: polyclonal
Host: Rabbit
Form: 100 ul of epitope affinity purified IgG (1 mg/ml) in PBS containing 1mg/ml BSA and 0.05% sodium azide.

Answer

Thank you for contacting us. For a purified antibody (such as the one you are trying to purify) you would want to use either ab102783 or ab102784. They are exactly the same, except the first is for one purification and the second is forthree purifications, so depending on whether you may need to purify in the future you can choose which size is more suitable for you.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Inquiry: To whom it may concern, I have IgG antibody in cell culture supernatant. I need to purify as much of the antibody as I can (2-5mg/ml). I can not use harsh conditions as I need to use the antibody for affinity assays. Can you please advise and give me quotes for the kits? Do you have a supplier in Sweden? Best wishes,

Read More
Answer

We have kits available for purifying antibodies from Tissue culture supernatants. The catalogue number is ab109207. Please check the datasheet; https://www.abcam.com/Antibody-TCS-Purification-kit-3-purifications-ab109207.html

1 test kit can cost €245 while 3 tests kit will cost €520. One kit will be enough to purify antibody from 10-50 ml of supernatant.

Please note if the antibody to be purified is in serum or other samples then kit ab109209 or ab102784 will be more suitable.

Question

Dear,
We just received the new batch of ab110363 (which is a 100µl volume, at a concentration of 78µg/ml, so a total of around 7,8 µg in total), together with the the proposed "tissue culture purification kit", which is designed for large volumes. According to the protocol, the antibodies should be in a 10 to 50 ml volume, and the kit is used to purify up to 5mg of antibody.... I don't understand why this kit has been advised; it seems totally unlogical to use such kit to purify an antibody af wich we only got like 7.8µg .
Could you provide us with some more explanation. I'm afraid that using this kit the problem only becomes worse !
Kind regards

Answer

Thank you very much for your email.
I am very sorry for this embarrassing error. We obviously should not have sent you this kit. I am very sorry again. Please accept my apologies for this error.
We do not have a purification kit specifically for tissue culture supernatant for small volumes. If you would like however, I can send you a free kit based on protein G. Indeed, we still do not know why the first kit, based on protein A, did not work. It might be just a problem of the kit/antibody or maybe this specific clone is not as good with protein A. It is up to you - I can either send you the protein G based kit ab128747 or again a kit of ab102784.
Please let me know how you would like to proceed. Again, all my apologies for this inconvenience.

Question

This purification kit says to use 10-40 mL. Will it not work if I only have one vial (100 uL) of antibody?

Read More
Answer

Thank you for your call last week and for your patience while I have been in touch with the lab regarding your enquiry.

I've heard back from the lab, and unfortunately this purification kit will not work with a small volume of tissue culture supernatant antibody. If you would be interested in ordering a larger quantity (10 or more vials) then please contact mailto:sales@abcam.com to see if we may be able to provide this antibody in a purified format.

Please let me know if you have any further questions or if there is anything else that we can do for you. Have a great day!

Question

Dear,
We have a number of concerns:
1) We were recently adviced to buy the antibody purification kit (ab102784) to remove azide from the monoclonal ab110636 (see letter below), which we need to be able to use in cell culture as indicated. In the mean time we have bought this kit together with a FITC-labelingskit and two new batches of DLK1 antibodies (ab110636 and ab21682). After clean up with ab102784, it was found that ab110636 did not bind to the adviced collums, infact the antibody eluted already with the first step, the bidingbuffer. Only a minor fraction could be recovered in the washing buffers and elution buffers. An overview of our concentration measurements is provided in the attached file. This finding was also confirmed by ICC wish failed to provide a signal on a positive cell sample.
For ab21682 whitch was purified in parallel we did not notice this problem, but we only need this antibody as a negative control. It is Ab110636 which we should obtain in a purified, azide free form. What is possible?
One of the goals was also to label the purified ab110636 with de labeling kit, which now cannot be used.
2) ab21682 has been tested for ICC using 2 conditions, one negative and a second with a stimulated expression of DLK1, it was compared for its specificity to 5 other DLK1 antibodies (see attached figure). Our conclusion is that ab21682 is not specific for its target, but shows a high aspecific background staining, which is problematic since this antibody is mentioned in a few publications, and is as such the first choice to buy ffrom the website. It is however doubtfull whether this antibody can be used for ICC, and should not be sold for this purpose, since the "background" signal could be misinterpreted. I did not test it on paraffin samples for IHC
Ab110636 on the contrary is highly specific.
What could you propose?

Answer

Thank you very much for your email and your patience.
In regards to the first issue, with the purification of ab110363, I had contacted the laboratory. There is nothing special with this clone. The only thing which might could explain the result is, that the ab110636 you received is at a low concentration. Therefore it could be too dilute to bind and elute efficiently. I can therefore propose to send you a new vial of ab110363 and a purification kit for tissue culture supernatant ab109207 for free, so you can perform the experiment. Please let me know whether you would like to accept this offer.
In regards to the ab21682 staining in ICC, I would be pleased to investigate this further. Can you please provide me with an image and the protocol details? I have attached a questionnaire which will help you to put the protocol details together. Once I have received this information, it will be easier for me to investigate and troubleshoot the results, as well as initiate internal actions if necessary. The specificity of the product is obviously very important. If the product is faulty, we will also replace it for you.
Thank you very much for your cooperation. I am looking forward to hear back from you.

Question

I have checked with customer and then informed as as follows:





First we treated antibody with modifier reagent and then this mixture in your Easylink Conjugate.



In this labelling reaction, after incubation quencher is added.

Read More
Answer

Thank you for your answer and confirming that your customer added the modifier. The modifier step is inherent to the protocol.
I have to repeat that this kit can only be used for purified antibodies. The antibodies need to be purified before the conjugation reaction.
ab102885 will label any available amine with FITC. ab91655 is not purified and therefore contains a lot of proteins that have free amines. All these free amines will interfere with the conjugation of the antibody.
I would like to summarize that ab102885 has to be purified before being labeled with the EasyLink FITC Conjugation Kit. The purification can be done with ab109207 (Antibody TCS Purification Kit):
