Description：Recombinant Human PSG5 Protein is produced by mammalian expression system and the target gene encoding Gln35-Ile335 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：PSG5Alternative Names：Pregnancy-specific beta-1-glycoprotein 5; PS-beta-G-5; PSBG-5; Pregnancy-specific glycoprotein 5; Fetal liver non-specific cross-reactive antigen 3; FL-NCA-3 Entrez Gene (Human)： 5673; SwissProt (Human)： Q15238; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：QVTIEALPPK VSEGKDVLLL VHNLPQNLAG YIWYKGQLMD LYHYITSYVV DGQINIYGPA YTGRETVYSN ASLLIQNVTR EDAGSYTLHI IKRGDRTRGV TGYFTFNLYL KLPKPYITIN NSKPRENKDV LAFTCEPKSE NYTYIWWLNG QSLPVSPRVK QPIENRILIL PSVTRNETGP YECEIRDRDG GMHSDPVTLN VLYGPDLPSI YPSFTYYRSG ENLYLSCFAE SNPPAEYFWT INGKFQQSGQ KLSIPQITTK HRGLYTCSVR NSATGKESSK SMTVEVSAPS GIGRLPLLNP IVDHHHHHHDirections 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.
