Anti pd 1 and anti pd l1

Manufactured by Cell Signaling Technology

Anti-PD-1 and anti-PD-L1 are antibodies used in immunoassays. Anti-PD-1 binds to the PD-1 receptor, while anti-PD-L1 binds to the PD-L1 protein. These antibodies can be used to study the interaction between PD-1 and PD-L1, which is involved in the regulation of the immune response.

Western blotting was performed as described previously [9 (link)]. Briefly, cell lysates were prepared by resuspending cell pellets in 1% NP-40, 10 mM Tris, 140 mM NaCl, 0.1 mM PMSF, 10 mM iodoacetamide, 50 mM NaF, 1 mM EDTA, 0.4 mM sodium orthovanadate, 10 μg/mL leupeptin, 10 μg/mL pepstatin, and 10 μg/mL aprotinin and lysing on ice for 30 min. Cell lysates were centrifuged at 12,000 × g for 15 min to remove nuclei and cell debris. Protein concentration of the soluble extracts was determined by using the Bradford protein assay (Bio-Rad). Fifty micrograms of protein (per lane) was separated by 10% SDS-PAGE and transferred to PVDF membranes, which were probed for indicated antibody: anti-PD-1 and anti-PD-L1 (Cell Signaling Technology); anti-c-Myc (Abcam); and anti-beta-actin (Sigma-Aldrich). Proteins were detected with ECL (GE Healthcare Amersham).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
