    5 kDa PEG conjugated to KLH by a MBS linker.

  • ポジティブ・コントロール
    • PEGylated protein
  • 特記事項

    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.

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...
