蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 27.1 kDa. The protein migrates as 30-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记（Labeling）
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Protocol
背景（Background）
BLAME (B-lymphocyte activator macrophage expressed) is also known as SLAM family member 8(SLAMF8), CD353. BLAME is a cell surface receptor that is expressed upon activation of macrophages (MΦs) by IFN-γ or bacteria, is a negative regulator of ROS in response to Gram+ and Gram- bacteria. May play a role in B-lineage commitment and/or modulation of signaling through the B-cell receptor. SLAMF8 is a costimulatory molecule that affects the activation of macrophages in inflammation and in immunosuppression and inflammation response to glioma cells could aid immunotherapy for glioma.
