常规说明
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

ELISA assay using 5 µg/mL Anti-AFP RabMAb as the capture antibody and 0.5 µg/mL Anti-PEG-47-Biotin RabMAb (unpurified ab53449) as the detection antibody. HRP-avidin (1/3000) used for anti-PEG-47 detection. This ELISA assay could detect YCA1017 peptide-PEG antigen at a concentration as low as 0.9 ng/mL.
-
Direct ELISA assay using 63 ng/mL of antigen (GCSF-PEG) to coat the plate. HRP-avidin (1/3000) was used for the detection of varying amounts of anti-PEG-47-Biotin (unpurified ab53449).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Polyethylene glycol antibody [PEG-B-47b] (Biotin) (ab53449)
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human cerebral cortex tissue showing negative staining with purified ab53449 at 1/250. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.
