Description: Recombinant Human KLK3 Protein (Ile25-Pro261) is produced by mammalian expression system and the target gene encoding Ile25-Pro261 is expressed with a 6His tag at the C-terminus. Form: Liquid in a 0.2 μM filtered solution of 20mM Tris-HCl, 150mM NaCl, 1mM CaCl2, pH 7.5. 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 reducing SDS-PAGE.Chemical Structure : IVGGWECEKH SQPWQVLVAS RGRAVCGGVL VHPQWVLTAA HCIRNKSVIL LGRHSLFHPE DTGQVFQVSH SFPHPLYDMS LLKNRFLRPG DDSSHDLMLL RLSEPAELTD AVKVMDLPTQ EPALGTTCYA SGWGSIEPEE FLTPKKLQCV DLHVISNDVC AQVHPQKVTK FMLCAGRWTG GKSTCSGDSG GPLVCNGVLQ GITSWGSEPC ALPERPSLYT KVVHYRKWIK DTIVANPVDH HHHHH 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 : Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
