Description：Recombinant Human CDKN1A Protein is produced by E. coli expression system and the target gene encoding Ser2-Pro164 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 7.2.Gene Symbol：CDKN1AAlternative Names：CAP20; CDKN1; CIP1; MDA6; PIC1; SDI1; WAF1; Cyclin-dependent kinase inhibitor 1; CDK-interacting protein 1; Melanoma differentiation-associated protein 6; MDA-6; p21 Entrez Gene (Human)： 1026; SwissProt (Human)： P38936; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：SEPAGDVRQN PCGSKACRRL FGPVDSEQLR RDCDALMAGC IQEARERWNF DFVTETPLEG DFAWERVRGL GLPKLYLPTG PRRGRDELGG GRRPGTSPAL LQGTAEEDHV DLSLSCTLVP RSGEQAEGSP GGPGDSQGRK RRQTSMTDFY HSKRRLIFSK RKPLEHHHHH HDirections 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.
