Biotinylated Human BAFF (N-Avi

Biotinylated Human BAFF (N-Avi-Fc) (CY92)

产品说明(Description)

Biotinylated Recombinant Human B-cell-activating factor is produced by our Mammalian expression system and the target gene encoding Ala134-Leu285 is expressed with a Avi tag and a Fc tag at the N-terminus.

Accession #: Q9Y275

Known as: Tumor necrosis factor ligand superfamily member 13B; TNFSF13B; B lymphocyte stimulator; BLyS; B-cell-activating factor; BAFF; Dendritic cell-derived TNF-like molecule; TNF- and APOL-related leukocyte expressed ligand 1; TALL-1; CD257; TNFSF20; ZTNF4

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

 

质量控制(Quality Control)

Purty:        Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

Biotin:Protein Ratio  The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

 

复溶(Reconstitution)

Always centrifuge tubes before opening. Do not mix by vortex or pipetting. 

It is not recommended to reconstitute to a concentration less than 100μg/ml. 

Dissolve the lyophilized protein in distilled water.

Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

 

保存(Storage)

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. 

Reconstituted protein solution can be stored at 4-7°C for 2-7 days.  

Aliquots of reconstituted samples are stable at < -20°C for 3 months.

 

背景(Background)

B-cell activating factor (BAFF), also known as BLyS, TALL-1, THANK, and TNFSF13B, is a transmembrane glycoprotein in the TNF ligand superfamily. BAFF is a cytokine and serves as a ligand for receptors TNFRSF13B (TACI), TNFRSF17 (BCMA), and TNFRSF13C (BAFFR). BAFF can promotes the survival, proliferation and maturation of B lymphocytes, which are key elements in the pathogenesis of systemic lupus erythematosus (SLE). This cytokine is encoded on TNFSF13B gene, and diverse single-nucleotide polymorphisms have been associated with susceptibility in diferent autoimmune disorders. BAFF is a transmembranal protein expressed on myeloid lineage and some epithelial cells, through diferent stimuli such as IFN-γ, IFN-α, interleukin (IL)-10, Toll-like receptors (TLR)-3, TLR-4 and TLR-7.
