Active Recombinant Human CCL23 Protein (99 aa)

• Cat.No.: CCL23-072C
• Product Overview: Recombinant Human CCL23 Protein without tag was expressed in E. coli.

Specification

• Description: MIP-3/CCL23 is a CC chemokine that signals through the CCR1 receptor. MIP-3 chemoattracts monocytes, resting T-lymphocytes and neutrophils, but does not chemoattract activated lymphocytes. Additionally, MIP-3 has been shown to inhibit colony formation of bone marrow myeloid immature progenitors. Alternative splicing of the MPIF1 gene results in two mRNAs that encode a short (CKβ8) and a long (CKβ81) isoform of the chemokine. CKβ8 cDNA encodes a 120 amino acid (aa) residue precursor protein with a putative 21 aa residue signal peptide that is cleaved to generate a 99 aa residue mature CKβ8 (aa 22 120). Additional N terminal processing of the 99 aa residue variant can generate a 75 aa residue CKβ8 (aa 46 120) that is significantly more active than the 99 aa residue variant.
• Source: E. coli
• Species: Human
• Form: Sterile Filtered White lyophilized (freeze-dried) powder.
• Bio-activity: Fully biologically active when compared to standard. Determined by its ability to chemoattract human T cell population using a concentration range of 10.0 -50.0 ng/mL, corresponding to a Specific Activity of ＞2 × 10^4 IU/mg.
• Molecular Mass: 11.3 kDa, a single, non-glycosylated polypeptide chain containing 99 amino acids.
• Protein length: 99
• AA Sequence: RVTKDAETEFMMSKLPLENPVLLDRFHATSADCCISYTPRSIPCSLLESYFETNSECSKPGVIFLTKKGRRFCANPSDKQVQVCMRMLKLDTRIKTRKN
• Endotoxin: Less than 1 EU/mg of rHuMIP-3/CCL23 as determined by LAL method.
• Purity: >97% by SDS-PAGE and HPLC analyses.
• Storage: This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 to -70 centigrade. Avoid repeated freeze/thaw cycles.
• Storage Buffer: Lyophilized from a 0.2mm filtered concentrated solution in 20mM PB, pH 7.4, 150mM 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 centigrade. Further dilutions should be made in appropriate buffered solutions.
