Description |
The B cell-activating factor from the TNF family (BAFF), is emerging as an important regulator of B cell and T cell responses. BAFF was originally identified as a factor responsible for B cell survival and maturation. BAFF binds to several receptors. These include transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI), BAFF-R (BR3), and B cell maturation Ag (BCMA). BAFF-R appears to be particularly important for the regulation of B cell survival and maturation in the spleen, because A/WySnJ mice expressing a defective BAFF-R have disrupted B cell maturation, similar to that seen in BAFF-deficient mice. |
Accession |
Q9Y275 |
Functions |
The ED(50) was determined by a cell proliferation assay using anti-IgM stimulated murine B cells, and is less than 2.0 ng/mL, corresponding to a specific activity of 5.0 x 10^5 IU/mg |
Formulation |
Recombinant Human BAFF was lyophilized from a 0.2 ?m filtered solution in PBS, pH 7.5. |
Solubility |
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. |
Appearance |
Lyophilized Powder |
Molecular Weight |
18 |
Purity |
>95% as determined by SDS-PAGE |
Concentration |
<1.0 EU/μg of recombinant protein as determined by the LAL method. |
Shipping Condition |
Ambient Temperature |
Storage Condition |
The lyophilized protein is stable for at least one year from date of receipt at -70?C. Upon reconstitution, this cytokine 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. |
