Opis

Opis ogólny

PD-L1, also known as CD274 or B7H1, stands for programmed cell death ligand 1. It is a type I transmembrane protein that is thought to repress immune responses by binding to its receptor (PD1), thus inhibiting T-cell activation, proliferation, and cytokine production. It contains V-like and C-like immunoglobulin domains. PD-L1 expression is regulated by various cytokines, such as TNF-α or LPS (ISSN: 1848-7718). Increased expression of this protein in certain types of cancers, e.g., renal cell carcinoma or colon cancer, correlates with poor prognosis.Alpaca derived anti-PD-L1 VHH single domain antibody (molecular weight: 14.4kDa), expressed in E. coli under conditions free from animal derived components. It has a 6His tag at its C-terminal.
Single-domain antibody (sdAb), also called nano-antibody, is the variable region isolated from the antigen-binding variable domain (VHH) of camelid heavy-chain-only antibody. It lacks light chains and a first constant domain(CH1). This configuration confers a number of unique advantages over conventional monoclonal antibodies. The small size of just 15 kDa (2~4 nm), single-domain antibody is the smallest antigen-binding fragment that can easily penetrate tissues, allowing them to bind epitopes that are inacessible to conventional antibodies. The small size and monovalency makes it a superior tool in microsopy. These single-domain antibodies offer superior chemical (wide variety of pH, urea, etc) and thermal stability and increased solubility than conventional antibodies. All our antibodies are tested to ensure the highest level of specificity, sensitivity and reproducibility.
