Description：Recombinant Human TAC1 Protein is produced by E. coli expression system and the target gene encoding Glu20-Arg129 is expressed with a 6His tag at the N-terminus.Form：Liquid in a 0.2 μM filtered solution of 20mM Tris-HCI, 150mM NaCl, 10% glycerol, 2M Urea, 1mM EDTA, pH8.0.Gene Symbol：TAC1Alternative Names：NKA; NKNA; TAC2; Protachykinin-1; PPT Entrez Gene (Human)： 6863; SwissProt (Human)： P20366; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MEEIGANDDL NYWSDWYDSD QIKEELPEPF EHLLQRIARR PKPQQFFGLM GKRDADSSIE KQVALLKALY GHGQISHKRH KTDSFVGLMG KRALNSVAYE RSAMQNYERR RDirections 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：Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
