NOT FOR HUMAN USE. 技术规格Tag | None | 种属 | Human | 表达系统 | E.coli | Accession# | P42224 | Source | E.coli | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4. | Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. | Reconstitution | Dissolve the lyophilized protein in distilled water. | Purity | Greater than 90% as determined by reducing SDS-PAGE. | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | Background | Signal Transducer and Activator of Transcription 1-Alpha/Beta (STAT1) contains one SH2 domain and belongs to the transcription factor STAT family. When tyrosine- and serine-phosphorylated, STAT1 can form a homodimer termed IFN-gamma-activated factor (GAF), migrate into the nucleus and bind to the IFN gamma activated sequence (GAS) to drive the expression of the target genes, inducing a cellular antiviral state. STAT1 functions as signal transducer and transcription activator that mediates cellular responses to interferons. Defects in STAT1 are the cause of STAT1 deficiency complete and familial candidiasis type 7. |
