Optimized DNA sequence encoding Human BCMA extracellular domain was expressed in Escherichia Coli.

Molecular weight:

Recombinant BCMA is a disulfide-linked monomer protein consisting of 54 amino acid residue subunits, and migrates as an approximately 6kDa protein under non-reducing and reducing conditions in SDS-PAGE.

>95%, as determined by SDS-PAGE and HPLC

Biological Activity:
The ED(50) was not determined.

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Recombinant BCMA was lyophilized from a 0.2 μm filtered 30% acetonitrile, 0.1% TFA solution pH 7.5.

A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

The lyophilized protein is stable for at least 2 years from date of receipt at -20° C.
Upon reconstitution, this product can be stored in working aliquots at 2° - 8° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity.

Avoid repeated freeze/thaw cycles.

BCMA (B cell maturation) is a nonglycosylated integral membrane type I protein that is preferentially expressed in mature B lymphocytes.The N-terminal part of both mouse and human proteins contains a conserved six- cysteine motif. BLyS binds to three receptors of the TNF receptor family (B cell maturation antigen BCMA, TACI, and BAFF-R), all of which are expressed by mature B cells.
