Recombinant Human CXCR4 (N-Fc)

Recombinant Human CXCR4 (N-Fc) (C16M)

产品说明(Description)

Recombinant Human C-X-C Chemokine Receptor Type 4 is produced by our Mammalian expression system and the target gene encoding Met1-Ser46 is expressed with a Fc tag at the N-terminus.

Accession #: P61073

Known as: CXCR4; CD184; Fusin; D2S201E; FB22; HM89; HSY3RR; LAP3; LCR1; LESTR; NPY3R; NPYR; NPYRL; NPYY3R; WHIM

 

制剂(Formulation)

Lyophilized from a 0.2 μm filtered solution of 50mM Tris-HCl,100mM Glycine, pH7.5.

 

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.

 

 

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)

C-X-C chemokine receptor type 4 (CXCR4) is an alpha-chemokine receptor specific for stromal-derived-factor-1 (SDF-1 also called CXCL12), a molecule endowed with potent chemotactic activity for lymphocytes. This receptor is one of several chemokine receptors that HIV isolates can use to infect CD4+ T cells. CXCR4 stands out for its pleiotropic roles in both physiological and pathological conditions and it represents a crucial target in drug development. CXCL12 is the principal CXCR4 specific ligand and that the pro-inflammatory chemokine macrophage migration inhibitory factor (MIF) is also able to bind and activate CXCR4.
