Description：Recombinant Human CPA2 Protein is produced by Mammalian expression system and the target gene encoding Leu17-Tyr417 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 7.5.Gene Symbol：CPA2Alternative Names：Carboxypeptidase A2 Entrez Gene (Human)： 1358; SwissProt (Human)： P48052; Purity：Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.Chemical Structure：LETFVGDQVL EIVPSNEEQI KNLLQLEAQE HLQLDFWKSP TTPGETAHVR VPFVNVQAVK VFLGSQGIAY SIMIEDVQVL LDKENEEMLF NRRRERSGNF NFGAYHTLEE ISQEMDNLVA EHPGLVSKVN IGSSFENRPM NVLKFSTGGD KPAIWLDAGI HAREWVTQAT ALWTANKIVS DYGKDPSITS ILDALDIFLL PVTNPDGYVF SQTKNRMWRK TRSKVSGSLC VGVDPNRNWD AGFGGPGASS NPCSDSYHGP SANSEVEVKS IVDFIKSHGK VKAFITLHSY SQLLMFPYGY KCTKLDDFDE LSEVAQKAAQ SLRSLHGTKY KVGPICSVIY QASGGSIDWS YDYGIKYSFA FELRDTGRYG FLLPARQILP TAEETWLGLK AIMEHVRDHP YVDHHHHHHDirections 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.
