Anti-E. coli antibody (ab13627)

Malheureusement la méthode de purification pour cet anticorps confidentielle, et donc nous ne pouvons pas partager les détails. Cependant, nous pouvons vous dire que la méthode utilise une précipitation du sulfate de sodium et donne une pureté équivalente à une méthode de précipitation de sulfate / méthode DEAE.

Thank you for contacting us.

The concentration of ab13627 is approximately 4mg/ml.

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

Thank you for your inquiry.

I am happy to confirm that the concentration of ab13627 is approximately 4 mg/ml.

I hope this information is helpful and wish you a good weekend.

Thank you for your enquiry.

Information in our files indicates this antibody has tested positive against the following serotypes:


O157:H7

O20

O125

O55

O111

K12

Unfortunately, I am sorry to confirm we have not specifically tested to see if it will recognize other H proteins of the O157 serotype. Information we have from the originators indicates they expects it react with many (if not all) O and K serotypes but the antibody has not been specifically tested against the H antigens.

I hope this will be helpful. If you have any further questions, please do not hesitate to contact us.

I apologize as I missed it.

Lab has confirmed the ab13627 is specific to O157, O20, O125, O55, O111 & K12 serotypes. However, they also advised that the immunogen was a mixture of several different serotypes and expect that the antibody would react with other O and K serotypes.

I hope this info will help.

The concentration is 4mg/ml.
I hope this is helpful. Please contact us again if you have any further information.

Thank you for your telephone call yesterday afternoon. I am sorry to hear you have some concerns regarding the results from this antibody.

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for IF. In the event that a product is not functioning in the tested applications and species cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

As discussed on the telephone, I would like to investigate this particular case further for you, and also obtain more information for our quality monitoring records. In order to proceed with this, I have enclosed a technical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily.

I would appreciate if you could also provide an image of the staining which would help us to assess the results.

In answer to your questions regarding why the PCR is showing indication of presence of other bacteria, there are many factors to consider:

1. The IHC staining may need some optimization to ensure the staining of ecoli is accurate and correct, We can look at this with you and provide assistance.

2. The accuracy of the laser cutting, it may be cutting out other unstained cells.

3. The sterility of the samples, all the reagents and equipment are very important to ensure no contamination by other bacteria which may be picked up with the PCR.

4. How well the PCR is working, including negative controls? Could you confirm what other bacteria are being detected by the PCR? Do you have any further information or data?

Thank you for your time and cooperation. We look forward to receiving the completed questionnaire.

Thank you for your enquiry and your interest in our products.

I can confirm that ab13627 (anti-E. coli antibody) is not an affinity purified product so the IgG concentration is not been determined on a regular basis. We normally quantify and publish the concentration for affinity purified antibodies on the on-line product datasheets.

However, I can release that IgG concentration of our recent batch is 4.0 mg/ml. It is important, however, to emphasize that we currently do not have any experience in conjugating this particular antibody to Dynabeads.

If you need any further assistance in the future, please do not hesitate to contact me.

Thank you for contacting us.

I can confirm that I have sent an email to my colleague in lab for the information you requested.

I will get back to you with a reply soon.

Thank you for your reply.

I have passed yourinformation and the discount information on to my colleagues on our customer services team, and they will be sending your proforma shortly.

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