Description: Recombinant Human KLK3 Protein is produced by Mammalian expression system and the target gene encoding Ala18-Pro261 is expressed with a 6His tag at the C-terminus. Form: Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 50mM NaCl, 15% Sucrose, 0.05% Tween80, 200mM L-Arginine, pH8.5 Gene Symbol: KLK3 Alternative Names: APS; Prostate-specific antigen; PSA; Gamma-seminoprotein; Seminin; Kallikrein-3; P-30 antigen; SemenogelaseEntrez Gene (Human): 354SwissProt (Human): P07288Purity : Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure : APLILSRIVG GWECEKHSQP WQVLVASRGR AVCGGVLVHP QWVLTAAHCI RNKSVILLGR HSLFHPEDTG QVFQVSHSFP HPLYDMSLLK NRFLRPGDDS SHDLMLLRLS EPAELTDAVK VMDLPTQEPA LGTTCYASGW GSIEPEEFLT PKKLQCVDLH VISNDVCAQV HPQKVTKFML CAGRWTGGKS TCSGDSGGPL VCNGVLQGIT SWGSEPCALP ERPSLYTKVV HYRKWIKDTI VANPVDHHHH HHDirections 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.
