Background
Programmed death-ligand 1 (PD-L1) also known as cluster of differentiation 274 (CD274) or B7 homolog 1 (B7-H1) is a protein that in humans is encoded by the CD274 gene. The formation of the PD-1 receptor / PD-L1 or B7.1 receptor /PD-L1 ligand complex transmits an inhibitory signal which reduces the proliferation of these CD8+ T cells at the lymph nodes. PD-1 is also able to control the accumulation of foreign antigen specific T cells in the lymph nodes through apoptosis, which is further mediated by a lower regulation of the gene Bcl-2.

Sterility Testing
Creative Biolabs provides sterility testing in accordance with USP and EP regulations. All of our sterility testing is performed in an isolator or clean room environments. The cell line has been screened using the membrane filtration testing methods to confirm the absence of aerobic, anaerobic and fungi microorganisms.
Identity Testing
Identity testing is required for newly established cell lines. Isoenzyme analysis is used to confirm the identity of the species of a cell line. Alternative methods for identity testing include DNA fingerprinting, STR analysis and karyology.
Virological Safety Testing
A broad range of viruses is susceptible to affecting human cell lines. We can provide in vivo/vitro virus safety assays by utilizing various animal systems. These viruses include: adventitious viruses, bovine viruses, human and simian viruses, porcine viruses, retrovirus and rodent viruses.
Genetic Stability Testing
We perform cell genetic stability studies under ICH guidelines. We can provide guidance on the appropriate testing program upon your requirements.
Mycoplasma Testing
The cell line has been screened using the luciferase based mycoplasma detection kit to confirm the absence of mycoplasma species.
