Description：Recombinant Human FAM19A4 Protein is produced by E. coli expression system and the target gene encoding Ser35-Arg140 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：FAM19A4Alternative Names：TAFA4; Protein FAM19A4; Chemokine-like protein TAFA-4 Entrez Gene (Human)： 151647; SwissProt (Human)： Q96LR4; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MSSQHLRGHA GHHQIKQGTC EVVAVHRCCN KNRIEERSQT VKCSCFPGQV AGTTRAQPSC VEASIVIQKW WCHMNPCLEG EDCKVLPDYS GWSCSSGNKV KTTKVTRDirections 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.
