Description：Recombinant Human B3GNT1 Protein is produced by mammalian expression system and the target gene encoding Asp43-Cys415 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of PBS, pH 7.4.Gene Symbol：B3GNT1Alternative Names：B3GNT6; N-acetyllactosaminide beta-13-N-acetylglucosaminyltransferase; I-beta-13-N-acetylglucosaminyltransferase; iGnT; Poly-N-acetyllactosamine extension enzyme; UDP-GlcNAc:betaGal beta-13-N-acetylglucosaminyltransferase 1 Entrez Gene (Human)： 11041; SwissProt (Human)： O43505; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：DQYFEFFPPS PRSVDQVKAQ LRTALASGGV LDASGDYRVY RGLLKTTMDP NDVILATHAS VDNLLHLSGL LERWEGPLSV SVFAATKEEA QLATVLAYAL SSHCPDMRAR VAMHLVCPSR YEAAVPDPRE PGEFALLRSC QEVFDKLARV AQPGINYALG TNVSYPNNLL RNLAREGANY ALVIDVDMVP SEGLWRGLRE MLDQSNQWGG TALVVPAFEI RRARRMPMNK NELVQLYQVG EVRPFYYGLC TPCQAPTNYS RWVNLPEESL LRPAYVVPWQ DPWEPFYVAG GKVPTFDERF RQYGFNRISQ ACELHVAGFD FEVLNEGFLV HKGFKEALKF HPQKEAENQH NKILYRQFKQ ELKAKYPNSP RRCVDHHHHH HDirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
