Endotoxin level is <0.1 ng/ug of protein (<1 EU/ug).
Measured by its ability to induce TNF-alpha production by human PBMCs.
Activity assay SDS-PAGE The optimal working dilution should be determined by the end user.
Lyophilized from 0.5x PBS, pH 8.0.
Store at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
The human leukocyte differentiation antigen CD23 (FCE2) is a key molecule for B-cell activation and growth. It is the low-affinity receptor for IgE. The truncated molecule can be secreted, then functioning as a potent mitogenic growth factor.[supplied by OMIM
