BAFF/TNFSF13B Trimer Protein, Human, Recombinant (His & Flag)

B-cell activating factor (BAFF) also known as tumor necrosis factor ligand superfamily member 13B is a protein that in humans is encoded by the TNFSF13B gene.BAFF is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. This cytokine is a ligand for receptors TNFRSF13B/TACI, TNFRSF17/BCMA, and TNFRSF13C/BAFF-R.

Species	Human
Expression System	HEK293
Tag	N-His-Flag
Accession Number	Q9Y275-1
Synonyms	BLyS, TALL-1, TNFSF13B, DTL, TNFSF20, TALL-1δ BAFF, TALL-1delta BAFF, TALL1δ4 BAFF, ZTNF4, TALL1, THANK, BAFF, TALL1Delta4 BAFF, CD257
Construction	Recombinant Human BAFF/TNFSF13B/CD257 Trimer Protein is expressed from HEK293 with His tag and Flag tag at the N-Terminus. It contains Thr141-Leu285.[Accession \|Q9Y275-1]
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	The protein has a predicted MW of 52.4 kDa. Due to glycosylation, the protein migrates to 53-60 kDa based on Tris-Bis PAGE result.

Endotoxin	Less than 1EU per μg by the LAL method.
Formulation	Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability & Storage	-20 to -80°C for 12 months as supplied from date of receipt. -20 to -80°C for 3-6 months in unopened state after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Shipping	In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
