Recombinant Human MIP-1 is a single, non-glycosylated, polypeptide chain containing 69 amino acids and having a molecular mass of 7620 Dalton. Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be, Ala-Pro-Met-Gly-Ser. Dimers and Aggregates: 1% as determined by silver-stained SDS-PAGE gel analysis. Biological Activity: rHuMIP-1 is fully biologically active when compared to standard. The Activity is calculated by the ability to chemoattract Human blood monocytes using a concentration of 5-20ng/ml. Endotoxin: 0.1ng/ug (IEU/ug) of rHuMIP-1. Protein Content: Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280nm. 2. Analysis by RP-HPLC, using a standard solution of MIP-1 as a Reference Standard. Reconstitution: Reconstitute the lyophilized rHuMIP-1 in sterile 18M -cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Storage and Stability: Lyophilized powder may be stored at 4°C for short-term only. Reconstitute to nominal volume by adding sterile dH2O and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. |
Source: E. coli Purity: 95% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified. Concentration: ~0.1mg/ml Form: Supplied as a lyophilized powder. No additives. Important Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
