Recombinant Human BAFFR (C-6His) (C16C)

产品说明(Description)

 

Recombinant Human Tumor Necrosis Factor Receptor Superfamily Member 13C is produced by our Mammalian expression system and the target gene encoding Ser7-Ala71 is expressed with a 6His tag at the C-terminus.

Accession #: Q96RJ3

Known as: BAFF R; BAFFR; BR3; CD268; TNFRSF13C

 

制剂(Formulation)

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

 

质量控制(Quality Control)

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

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

 

Bioactivity-ELISA:
Immobilized Human BAFF-Fc(Cat#CU71) at 2μg/ml (100 μl/well)can bind Human BAFFR-His(Cat#C16C). The ED50 of Human BAFFR-His(Cat#C16C)is 7.67 ng/ml.		Immobilized Human BAFFR-His(Cat#C16C)at 2μg/ml (100 μl/well)can bind Anti-Human BAFFR mAb(Cat#NC033). The ED50 of Anti-Human BAFFR mAb(Cat#NC033)is 33.25ng/ml.

 

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)

Tumor necrosis factor receptor superfamily, member 13C (TNFRSF13C) also known as B-cell-activating factor receptor (BAFFR) and CD268 antigen, is a member of the tumor necrosis factor receptor superfamily. BAFF promotes the survival of B cells and is essential for B cell maturation. BAFF binds to three TNF receptor superfamily members: B-cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF13C). These receptors are type III transmembrane proteins that lack a signal peptide. BAFF R is highly expressed in spleen, lymph node and resting B cells. It is also expressed at lower levels in activated B cell, in resting CD4+ T cells, in thymus and peripheral blood leukocytes. BAFF knockout mice lack mature B cells. Similarly, A/WySnJ mice that are defective in BAFF-R intracellular signaling also lack mature B cells, suggesting that BAFF R is the critical receptor for BAFF during B lymphopoiesis. It has been proposed that abnormally high levels of BAFFR/TNFRSF13C (CD268) may contribute to the pathogenesis of autoimmune diseases by enhancing the survival of autoreactive B cells.
