产品描述 概述Recombinant Human Histone Chaperone ASF1A is produced by our E.coli expression system and the target gene encoding Met1-Met204 is expressed with a T7 tag at the N-terminus, 6His tag at the C-terminus. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格Tag | C-6His, N-T7 tag | 种属 | Human | 表达系统 | E.coli | Accession# | Q9Y294 | Source | E.coli | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 1mM DTT, 150mM NaCl, pH 8.0. | 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 95% as determined by reducing SDS-PAGE. | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | Background | Human Histone Chaperone ASF1A (ASF1A) belongs to the H3/H4 family of histone chaperone proteins. ASF1A is ubiquitously expressed in many cells and tissues, interacting with histones H3 and H4. ASF1A cooperates with Chromatin Assembly Factor 1 to promote replication-dependent chromatin assembly and with HIRA to promote replication-independent chromatin assembly. In addition, ASF1A is necessary for the formation of senescence-associated heterochromatin foci (SAHF) and efficient senescence-associated cell cycle exit. |
