Cat#:RP-2055H;Product Name:Recombinant Human APOE4 Protein;Synonym:Apolipoprotein E, APO-E, Alzheimer Disease 2 (APOE*E4-Associated, Late Onset), Apolipoprotein E3, LDLCQ5, LPG, AD2, APOE.;Description:Apolipoprotein E4 Protein produced in E.coli is a single, non-glycosylated polypeptide chain containing a total of 306 amino acids including a His Tag at N-terminus and having a molecular mass of 35.2kDa. The Accession # is P02649 VAR_000652.;Source:E.coli;AA Sequence:MHHHHHHKVE QAVETEPEPE LRQQTEWQSG QRWELALGRF WDYLRWVQTL SEQVQEELLS SQVTQELRAL MDETMKELKA YKSELEEQLT PVAEETRARL SKELQAAQAR LGADMEDVRG RLVQYRGEVQ AMLGQSTEEL RVRLASHLRK LRKRLLRDAD DLQKRLAVYQ AGAREGAERG LSAIRERLGP LVEQGRVRAA TVGSLAGQPL QERAQAWGER LRARMEEMGS RT;Purity:Greater than 90% as determined by SDS-PAGE.;Bioactivity:Please contact us for detailed information;Formulation:Lyophilized from a sterile (0.2µm) filtered aqueous solution containing 10mM sodium phosphate, pH 7.5.;Stability:Recombinant Proteins are stable for up to 1 year from date of receipt at -70℃;Reconstitution:It is recommended to reconstitute the lyophilized APOE4 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.;Storage:Lyophilized APOE4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution APOE4 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.;
