Description: Recombinant Human CEACAM21 Protein is produced by mammalian expression system and the target gene encoding Trp35-Gly240 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 7.4. Gene Symbol: CEACAM21 Alternative Names: Carcinoembryonic antigen-related cell adhesion molecule 21Entrez Gene (Human): 90273SwissProt (Human): Q3KPI0Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : WLFIASAPFE VAEGENVHLS VVYLPENLYS YGWYKGKTVE PNQLIAAYVI DTHVRTPGPA YSGRETISPS GDLHFQNVTL EDTGYYNLQV TYRNSQIEQA SHHLRVYESV AQPSIQASST TVTEKGSVVL TCHTNNTGTS FQWIFNNQRL QVTKRMKLSW FNHVLTIDPI RQEDAGEYQC EVSNPVSSNR SDPLKLTVKS DDNTLGVDHH HHHH 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.
