产品说明(Description)

Recombinant Human Bone Marrow Stromal Antigen 2 is produced by our Mammalian expression system and the target gene encoding Asn49-Ser161 is expressed with a 6His tag at the C-terminus. 

Accession #: Q10589

Known as: Bone Marrow Stromal Antigen 2; BST-2; HM1.24 Antigen; Tetherin; CD317; BST2

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4.

 

质量控制（Quality Control） 

 

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

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

 

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 100 μg/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）

Bone Marrow Stromal Antigen 2 (BST2) is a single-pass type II membrane protein that belongs to the tetherin family. BST2 is predominantly expressed in the liver, lung, heart and placenta. BST2 is involved in the sorting of secreted proteins. BST2 is a human cellular protein which inhibits retrovirus infection by preventing the diffusion of virus particles after budding from infected cells. BST2 is initially discovered as an inhibitor to HIV-1 infection in the absence of Vpu, it has also been shown to inhibit the release of other viruses such as retroviruses, filoviruses, arenaviruses, and herpes viruses. BST2 may play a role in B-cell activation in rheumatoid arthritis.
