Description: Recombinant Human DR1 Protein is produced by E. coli expression system and the target gene encoding Ala2-Ile176 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, 1mM DTT, pH 8.0. Gene Symbol: DR1 Alternative Names: Protein Dr1; Down-regulator of transcription 1; Negative cofactor 2-beta; NC2-beta; TATA-binding protein-associated phosphoproteinEntrez Gene (Human): 1810SwissProt (Human): Q01658Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : ASSSGNDDDL TIPRAAINKM IKETLPNVRV ANDARELVVN CCTEFIHLIS SEANEICNKS EKKTISPEHV IQALESLGFG SYISEVKEVL QECKTVALKR RKASSRLENL GIPEEELLRQ QQELFAKARQ QQAELAQQEW LQMQQAAQQA QLAAASASAS NQAGSSQDEE DDDDIVEHHH HHH 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.
