Recombinant Human CXCL3 protein

• Cat.No.: CXCL3-16H
• Product Overview: Recombinant Human CXCL3 protein was expressed in Escherichia coli.

Specification

• Description: CXCL3, also named GRO-γ, is belonging to the CXC chemokine family and encoded by the gene CXCL3. CXCL3/GRO-γ shares 86 % amino acid sequence with CXCL1/GRO-α. All three human GROs (GRO-α, GRO-β, GRO-γ) are members of the intercrine alpha (chemokine C-X-C) subfamily of chemokines. This chemokine is secreted by monocytes and macrophages. The functional receptor for CXCL3 has been identified as CXCR2. Similar to other GRO proteins, CXCL3 is potent neutrophil attractants and activators. CXCL3 plays a role in inflammation and exert its effects on endothelial cells in an autocrine fashion. All three GROs can bind with high affinity to the IL-8 receptor type B.

• Endotoxin: Less than 1 EU/µg of rHuGRO-γ/CXCL3 as determined by LAL method.
• Purity: >97% by SDS-PAGE and HPLC analysis.
• Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70 centigrade as supplied. 1 month, 2 to 8 centigrade under sterile conditions after reconstitution. 3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
• 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 centigrade. Further dilutions should be made in appropriate buffered solutions.
