Recombinant Human GRO-β/CXCL2

Description :
FAQ COA 已发表文献 All three isoforms of GRO are CXC chemokines that can signal through the CXCR1 or CXCR2 receptors. The GRO proteins chemoattract and activate neutrophils and basophils. Recombinant Human GRO- is a 7.9 kDa protein consisting of 73 amino acids, including the ‘ELR’ motif common to the CXC chemokine family that binds to CXCR1 or CXCR2. Product Properties Synonyms MIP2-alpha Accession P19875 GeneID 2920 Source E.coli-derived Human GRO- Ala35-Asn107. Molecular Weight Approximately 7.9 kDa AA Sequence APLATELRCQ CLQTLQGIHL KNIQSVKVKS PGPHCAQTEV IATLKNGQKA CLNPASPMVK KIIEKMLKNG KSN Tag None Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 97% by SDS-PAGE and HPLC analyses. Biological Activity Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human CXCR2 transfected human 293 cells is in a concentration range of 10-100 ng/mL. Endotoxin Formulation Lyophilized from a 0.2 m filtered concentrated solution in 20 mM PB, pH 7.4, 50 mM NaCl. Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at -20 C. Further dilutions should be made in appropriate buffered solutions.
