Signaling lymphocytic activation molecule 1 is a protein that in humans is encoded by the SLAMF1 gene. Recently SLAMF1 has also been designated CD150 (cluster of differentiation 150). SLAMF1 belongs to the signaling lymphocytic activation molecule family. As other receptors from this family, SLAMF1 is expressed in different types of hematopoietic cells and it plays a role in the regulation of the immune system.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA723424) at 1/2,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
SLAM / CD150 was immunoprecipitated from 0.2 mg Raji cell lysate with HA723424 at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using HA723424 at 1/1,000 dilution. HRP Conjugated Anti-Rabbit IgG for IP Nano-secondary antibody at 1/5,000 dilution was used for 1 hour at room temperature.
