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: CDKN1A Alternative Names: CAP20; CDKN1; CIP1; MDA6; PIC1; SDI1; WAF1; Cyclin-dependent kinase inhibitor 1; CDK-interacting protein 1; Melanoma differentiation-associated protein 6; MDA-6; p21Entrez Gene (Human): 1026SwissProt (Human): P38936Purity : 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 H 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 : 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.
