产品描述 概述Recombinant Human Cerberus 1 is produced by our Mammalian expression system and the target gene encoding Thr18-Ala267 is expressed with a 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 | | 种属 | Human | | 表达系统 | Human cells | | Accession# | O95813 | | Source | Human Cells | | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 20mM NaAc-HAC，pH 4.5 | | 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 20mM NaAc-HAC. | | 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 | Cerberus 1 is a secreted glycoprotein that forms disulfide-linked homodimers. It is a cytokine member of the DAN domain family of BMP antagonists that includes DAN (DAND1), Gremlin/Drm (DAND2), PRDC (Protein Related to Dan and Cerberus, DAND3), and COCO/Dante (DAND5). DAN family members contain a cysteine knot domain that is homologous to that found in other TGF-beta superfamily ligands. At the onset of gastrulation, Cerberus 1 is transiently expressed in anterior endodermal structures in response to Nodal and Shh. Cerberus 1 binds BMP-4 and Nodal and inhibits their activities. The inhibitory functions of Cerberus favor mesodermal development in the anterior region of the gastrula and suppresses posterior mesodermal differentiation. In chick and Xenopus, Cerberus 1 also regulates, but is not required for embryonic left-right polarization, neurulation, and head and heart induction. |
