Description：Recombinant Human KLK4 Protein is produced by Mammalian expression system and the target gene encoding Ser27-Ser254 is expressed with a 6His tag at the C-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 8.0.Gene Symbol：KLK4Alternative Names：EMSP1; PRSS17; PSTS; Kallikrein-4; Enamel matrix serine proteinase 1; Kallikrein-like protein 1; KLK-L1; Prostase; Serine protease 17 Entrez Gene (Human)： 9622; SwissProt (Human)： Q9Y5K2; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：SCSQIINGED CSPHSQPWQA ALVMENELFC SGVLVHPQWV LSAAHCFQNS YTIGLGLHSL EADQEPGSQM VEASLSVRHP EYNRPLLAND LMLIKLDESV SESDTIRSIS IASQCPTAGN SCLVSGWGLL ANGRMPTVLQ CVNVSVVSEE VCSKLYDPLY HPSMFCAGGG QDQKDSCNGD SGGPLICNGY LQGLVSFGKA PCGQVGVPGV YTNLCKFTEW IEKTVQASVD HHHHHHDirections 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.
