Cat#:RP-4279H;Product Name:Recombinant Human LCN2 Protein;Synonym:Neutrophil gelatinase-associated lipocalin, NGAL, p25, 25 kDa alpha-2-microglobulin-related subunit of MMP-9, Lipocalin-2, Oncogene 24p3, LCN2.;Description:LCN2 Protein produced in E.coli is a homodimeric non-glycosylated polypeptide chains consisting of two 178 amino acids and having a molecular mass of 41.0kDa.?;Source:E.coli;AA Sequence:QDSTSDLIPA PPLSKVPLQQ NFQDNQFQGK WYVVGLAGNA ILREDKDPQK MYATIYELKE DKSYNVTSVL FRKKKCDYWI RTFVPGCQPG EFTLGNIKSY PGLTSYLVRV VSTNYNQHAM VFFKKVSQNR EYFKITLYGR TKELTSELKE NFIRFSKSLG LPENHIVFPV PIDQCIDG ;Purity:Greater than 95.0% as determined by:  (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.;Bioactivity:The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.5ng/ml, corresponding to a specific activity of > 2.0 × 1,000,000 IU/mg.;Formulation:LCN2 protein was lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4, with 0.05 % Tween-20.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Storage:Lyophilized LCN2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution LCN2 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).? Please prevent freeze-thaw cycles.;
