    The smallest PEG molecule which our antibody can detect is PEG750. Based on customer feedback, the largest PEG molecule detected is PEG 40K. Additionally, ab53449 detects both linear and branched PEG based on our in-house ELISA testing. 

    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.

Question

I found in your catalog the following antibodies: ab73909 and ab53449, which I would like to have. Could you please tell me how much these antibodies cost, how long will it take to deliver them? Is it possible to make them without glycerol, BSA and sodium azide?
Best regards

Read More
Answer

Thank you for your email.

Could you let me know how many glycerol, BSA and sodium azide free vials you would like to order? Once we have this information we can then confirm the supply.

Thank you very much for your cooperation. I will look forward to hearing from you soon.
