Murine MIP-2/CXCL2 (rMuMIP-2/CXCL2 )

• Catalog Number: orb1494918
• Category: Proteins
• Description: Macrophage Inflammatory Protein 2 (MIP-2) was originally identified as a heparin binding protein secreted from a murine macrophage cell line in response to endotoxin stimulation. Based on its protein and DNA sequences, MIP-2 is a member of the alpha (CXC) subfamily of chemokines. Similarly to other alpha chemokines, murine MIP-2 is a potent neutrophil attractant and activator. MIP-2 and KC can bind the murine interleukin 8 type B receptor homologue with high affinity. The expression of MIP-2 was found to be associated with neutrophil influx in pulmonary inflammation and glomerulonephritis, suggesting that MIP-2 may contribute to the pathogenesis of inflammatory diseases.
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• MW: 7.8 kDa, a single, non-glycosylated polypeptide chain containing 73 amino acids.
• Protein Sequence: AVVASELRCQ CLKTLPRVDF KNIQSLSVTP PGPHCAQTEV IATLKGGQKVCLDPEAPLVQ KIIQKILNKG KAN
• Source: Escherichia coli.
• Biological Activity: Fully biologically active when compared to standard. Determined by its ability to chemoattract total human neutrophils using a concentration range of 1.0-10.0 ng/ml, corresponding to a Specific Activity of ＞1 x 105 IU/mg.
• Endotoxins: Less than 1EU/mg of rMuMIP-2/CXCL2 as determined by LAL method.
• Storage: This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
• Buffer/Preservatives: Lyophilized from a 0.2mm filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.
• Note: For research use only
• Application notes: 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.
• Expiration Date: 6 months from date of receipt.
