- 10kD Spin Column (ab93349)

    Overview

    • Product name

      10kD Spin Column
    • Product overview

      The 10kD Spin Columns (ab93349) are disposable ultrafiltration devices for the concentration or deproteinization of biological samples.


      They can be used in either a swing bucket or fixed angle rotors which accept 2.0 mL centrifuge tube at maximum speed 10000 x g (5-10 mins). The vertical membrane design and thin channel filtration chamber minimizes membrane fouling and provides high speed concentration, even laden solutions. It is specifically designed with low internal surface and membrane area in order to achieve superior recovery from dilute solution.


      Maximum initial sample volume is 500µL. The dead stop volume is approximately 20-25µL.

    • Notes

      This product is manufactured by BioVision, an Abcam company and was previously called 1997 10K Spin Column. 1997-25 is the same size as the 25 unit size of ab93349.

      If working with cell or tissue lysates, we generally recommend the TCA Sample Deproteinization Kit or using a PCA/KOH Deproteinization protocol. If it is critical to use a spin column with a cell or tissue lysate then, to avoid blocking the filter, first centrifuge the lysate samples at ~14,000 rpm for 10-20 mins to pellet debris, and then use the resulting supernatant with the spin column.

    10kD spin column is an easy and reliable method to deproteinise the samples for downstream analysis to measure small molecules like NADPH.
    This kit provides a column to deprotenise small amount of protein lysate (upto 500 µL), in a bench top centrifuge.

    Question

    I'm using the NAD assay kit and I just purchased the 10kDa cutoff filters. I'm just wondering how long do you recommend spinning at 10,000 g to deproteinize 400ul of lysates ? Thanks

    Asked on Jul 21 2014

    Answer



    It is hard to predict how long will be required to spin the volume through the spin filter. It depends on how much protein is in the solution to be filtered as higher protein concentrations require longer spin times. I recommend spinning for 5 min at 4 deg C at first and then check to see how much volume has gone through. Then you will have a good idea as to how much longer will be required to push the remainder through.

    Answer

    Thank you for contacting us.

    Always ensure that you do not load more than 450 µl of diluted, non-viscous samples. I understand in the case of plasma you may not wish to dilute further. If you still have a difficulty in recovering a reasonable volume back, please centrifuge the samples for ˜30-45 min at 12000 rpm at 4°C.

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

    The columns have been tested to ensure that the samples are separated correctly. The fragments have been tested using several of our assay kits, verifying that analytes above/below 10 kDa are present in the correct fragment.

    Question

    I am using the 10kDa columns in preparing samples for a Lactate Assay. I collected the cells from the culture plate and passed them through a needle prior to adding the lysate onto the columns. When I spin down the columns at 10000rpm for 5 mins, I get about 50uL elute from 500uL input. I still see the majority of the lysate solution within the column and a small clump of solid at the bottom (likely the cellular debris). I wanted to know if all of the lysate input should be absorbed by the filter or if it is normal for most of it to remain in the column? Could the cell debris be blocking the column? Also, once the elute has come through, do I need to spec it to make sure I use equal amounts of protein concentrations in my assay, or do I assume I get the same amount from the columns?

    Answer

    You are exactly correct, insoluble material, whether from cells or tissue, needs to be removed prior to loading into the 10kDa spin column. Thus, after lysis/homogenization, centrifuge your sample to pellet the insoluble material. Then take the supernatant as your sample and load into the 10kDa spin column.

    Typically, an equivalent volume of sample will be loaded per well as the assay measures the amount of lactate present, but please refer to your lactate assay kit protocol. One of our lactate assay protocols is provided through the link below and uses an equivalent volume of sample per well:

    Asked on Jan 29 2013

    Answer

    We recommend the use of the 10 kDa filters irrespective of your immediate or later usage of the lysed samples. The filters help in separating out proteins which can chew up the analyte. You most likely will not get efficient results without the fliters.

    We carry 10 kD spin columns to assist in using this kit. The link for these columns is given below:

    Question

    Thanks for your answer.
    My concern was that using the assay buffer to homogenize the samples might generate a lot of bubbles (if the buffer has any kind of detergent).
    Can I extract lactate from samples using ethanol 80% and remove the proteins with perchloric acid?

    Asked on Nov 27 2012

    Answer

    Thanks for your response.
    I strongly recommend sticking to the kit protocol. Adding solutions (such as ethanol and perchloric acid) other than those provided in the kit will compromise the efficiency of lactate detection. The centrifugation step can be used to remove bubbles after homogenization in the assay buffer.
    I hope this response proves helpful. Please do not hesitate to reply or contact us with any additional questions.

    Asked on Nov 26 2012

    Answer

    Thank you for contacting Abcam.
    Since the lactate dehydrogenase (LDH) in tissue lysates degrades lactate, be sure to keep your samples at -80ºC. Below is our recommended homogenization protocol:
    1. Homogenize the tissue samples (should contain at least 2 million cells) in the assay buffer that is provided for 10-50 passes on ice.
    2. Centrifuge the sample and collect the supernatant.
    3. Load the supernatant onto a 10kda spin column (ab93349 https://www.abcam.com/10kd-spin-column-ab93349.html) for deproteinization to remove LDH. Use the eluate for your subsequent assays.
    To make sure that your readings from these samples are within the standard curve, we suggest using several doses of your sample when running your assay.
    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: Hello, I was wondering if you could please recommend me a product. I need to extract water-soluble metabolites from cell lysate in order to analyse them using a HPLC. So I'm looking for a microcentrifuge spin-through filter that will get rid of all the proteins and only yield the metabolites as a flow-through. Could you please tell me if I can use the 10 kD spin columns (ab93349) for this purpose? Or if I should get a filter with smaller pores such as a 3 kD filter? Many thanks,
