Description：Recombinant Human Prolactin Protein is produced by mammalian expression system and the target gene encoding Leu29-Cys227 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH7.4.Gene Symbol：PRLAlternative Names：Prolactin; PRL Entrez Gene (Human)： 5617; SwissProt (Human)： P01236; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：LPICPGGAAR CQVTLRDLFD RAVVLSHYIH NLSSEMFSEF DKRYTHGRGF ITKAINSCHT SSLATPEDKE QAQQMNQKDF LSLIVSILRS WNEPLYHLVT EVRGMQEAPE AILSKAVEIE EQTKRLLEGM ELIVSQVHPE TKENEIYPVW SGLPSLQMAD EESRLSAYYN LLHCLRRDSH KIDNYLKLLK CRIIHNNNCV DHHHHHHDirections 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 ddH2O. 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.
