CD47 CHO-K1 Cell line

Catalog #: 60602
Size: 2 vials

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 (SIRPα), on monocytes, macrophages or dendritic cells. 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.

CD47 CHO-K1 Cell line

Recombinant CHO-K1 cell that constitutively expresses full length human CD47 (NM_198793.2). Surface expression is confirmed by flow cytometry.
Host Cell line:
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.
Growth Media:

Thaw Medium 3 (BPS Cat. #60186): Ham’s F-12 medium (Hyclone # SH30526.01) supplemented with 10% FBS (Life technologies #26140-079), 1% Penicillin/Streptomycin (Hyclone SV30010.01).

Growth Medium 3B (BPS Cat. #79529): Thaw Medium 3 (BPS Cat. #60186) plus 500 μg/ml of Hygromycin B (Hyclone #SV30070.01) to ensure the recombinant expression.

Each vial contains ~3 x 10^6 cells in 1 ml of 10% DMSO in FBS.
Storage / Stability:
Store in liquid nitrogen immediately upon receipt.
This cell line is ideal for CD47 binding assays.
