Description: Recombinant Human PSG3 Protein is produced by mammalian expression system and the target gene encoding Gln35-Leu428 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: PSG3 Alternative Names: Pregnancy-specific beta-1-glycoprotein 3; PS-beta-G-3; PSBG-3; Pregnancy-specific glycoprotein 3; Carcinoembryonic antigen SG5Entrez Gene (Human): 5671SwissProt (Human): Q16557Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : QVTIEAEPTK VSKGKDVLLL VHNLPQNLAG YIWYKGQMKD LYHYITSYVV DGQIIIYGPA YSGRETVYSN ASLLIQNVTR EDAGSYTLHI VKRGDGTRGE TGHFTFTLYL ETPKPSISSS NLYPREDMEA VSLTCDPETP DASYLWWMNG QSLPMTHSLQ LSKNKRTLFL FGVTKYTAGP YECEIRNPVS ASRSDPVTLN LLPKLPKPYI TINNLNPREN KDVLAFTCEP KSENYTYIWW LNGQSLPVSP RVKRPIENRI LILPSVTRNE TGPYQCEIQD RYGGIRSYPV TLNVLYGPDL PRIYPSFTYY HSGENLYLSC FADSNPPAEY SWTINGKFQL SGQKLFIPQI TTKHSGLYAC SVRNSATGME SSKSMTVEVS APSGTGHLPG LNPLVDHHHH HH Directions 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.
