  • General notes

    Tween 20 usage: Tween 20 is a detergent that can interfere with ELISA and potentially other applications (often used in antibody dilution buffers, such as TBST) when using anti-PEG products. This is also the same case for other polyoxyethylene detergents. Therefore, it is recommended to avoid Tween 20 and other polyoxyethylene detergents
    when performing ELISA using anti-PEG products.

Asked on Jun 15 2016

Answer

To avoid Tween20 and other PEG-containing detergents, I recommend antigen retrieval buffers https://www.abcam.com/100x-citrate-buffer-ph-60-ab64236.html (100x Citrate Buffer pH 6.0, 50mL) or https://www.abcam.com/10x-citrate-buffer-ph-60-ab64214.html (10x Citrate Buffer pH 6.0, 125mL). Other citrate antigen retrieval buffers such as ab94674 and ab93678 do contain detergent that may interfere with detection of PEG by antibody ab94764.

Question

Is the antibody effective againist Methoxy-PEG (PEG-OMe) or standard PEG (PEG-OH). Moreover I want to know if you have idea of the affinity for short PEG chains (below 600Da).
For my application (immobilization of pegyated molecules on surfaces) it would be necessary to bind short PEG chains (200-300Da) even with low affinity.

Answer

I can confirm that we have determined that the specificity of the antibody (ab94764: Anti-Polyethylene glycol antibody) is to the linear backbone of PEG and that it will not recognize the methoxy group.

Question

Could you please explain me how this would change my results when this antibody is detected with an anti-rat IgG?

Asked on Jan 11 2012

Answer

Thank you for your reply. If the secondary antibody is directed against the heavy and light chains (H+L) of rat IgG, you will still be able to observe specific signal because the light chains are conserved between isotypes. If the secondary antibody is specific for a certain gamma heavy chain type (IgG1, 2, etc), then you will not observe specific signal.
