Cat#:RP-2214H;Product Name:Recombinant Human BD 2 Protein;Synonym:BD-2, hBD-2, Defensin beta 2, Skin-antimicrobial peptide 1, SAP1, DEFB4, DEFB102, DEFB2, DEFB4P, Beta-defensin 2.;Description:Beta Defensin-2 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing 41 amino acids and having a molecular mass of 4.3 kDa. The BD-2 is purified by proprietary chromatographic techniques.;Source:E.coli;AA Sequence:GIGDPVTCLK SGAICHPVFC PRRYKQIGTC GLPGTKCCKK P.;Purity:Greater than 98.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:Determined by the ability to chemoattract human dendritic immature cells at a concentration of 10-100ng/ml.;Formulation:The Human BD-2 was lyophilized from a 0.2µm filtered concentrated (1mg/ml) solution containing 20mM PB pH-7.4 and 130mM NaCl.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized Beta Defensin-2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized Beta Defensin-2 Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BD-2 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.;
