    Chemical/ Small Molecule corresponding to Polyethylene glycol conjugated to Keyhole Limpet Haemocyanin (KLH). KLH-PEG with a terminal methoxy group.

  • 特記事項

    This product is a recombinant rabbit monoclonal antibody.

    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.

    Produced using Abcam’s RabMAb® technology. RabMAb® technology is covered by the following U.S. Patents, No. 5,675,063 and/or 7,429,487.

Yes, ab53449 is purified before biotinylation. Protein A was used to purify this antibody.

Both antibodies ab51257 and ab53449 are the same clone (PEG-B-47). Product ab53449 is the biotinlyated version of ab51257.

Both ab51257 and ab53449 detect linear and branched PEG (based on our in-house ELISA results).
