Recombinant HEK293 cell line over-expressing full length human CD47 (NM_198793.2). Surface expression is confirmed by flow cytometry.
Mycoplasma testing: This cell line has been screened using the MycoAlert Mycoplasma Detection Kit (Lonza, Cat. #LT07-118) to confirm the absence of Mycoplasma contamination. MycoAlert Assay Control Set (Lonza, Cat. #LT07-518) was used as a positive control.
Host Species: human
Background
CD47 (also known as Rh-associated protein, GP42, integrin-associated protein (IAP), and neurophilin,) is an immunoglobulin-like protein that interacts with its receptor, Signal-regulatory protein alpha (SIRPalpha), on macrophages. This binding interaction regulates transmigration, oxidative burst cytokine production, and phagocytosis, creating a "don't eat me" signal. CD47 is ubiquitously expressed on the surface of normal cells, but is overexpressed in numerous cancer cells, where it is thought to contribute to the resistance of tumors to phagocyte-dependent clearance.
Application
Ideal for protein binding analyses and studying SIRPalpha receptor activity.
Host Cell
HEK293
Synonyms
leukocyte surface antigen CD47, Rh-related antigen, integrin-associated protein (IAP), antigenic surface determinant protein OA3, and MER6
Shipping Temperature
-80°C (dry ice)
