Recombinant Human CD72 (N-Trx-

Recombinant Human CD72 (N-Trx-6His) (CF13)

产品说明(Description)

Recombinant Human B-Cell Differentiation Antigen CD72 is produced by our E.coli expression system and the target gene encoding Arg117-Cys226 is expressed with a Trx, 6His tag at the N-terminus. 

Accession #: P21854

Known as: B-Cell Differentiation Antigen CD72; Lyb-2; CD72

 

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 90% 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)

B-Cell Differentiation Antigen CD72 (CD72) is a single-pass type II membrane protein. CD72 exists as a disulfide-linked homodimer and contains one C-type lectin domain. CD72 is expressed on B lineage cells, NK cells, monocytes, dendritic cells, and mast cells. CD72 is a ligand for CD5. CD72 associates with CD5, interacts with PTPN6/SHP-1 and plays a role in B-cell proliferation and differentiation. CD72 associates with CD79A in the B cell antigen receptor (BCR) complex following antigen stimulation and dampens BCR signaling through interactions with the phosphatase SHP-1.
