产品描述 概述Recombinant Human Polymeric Immunoglobulin Receptor is produced by our Mammalian expression system and the target gene encoding Lys19-Arg638 is expressed with a Fc 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-Fc | | 种属 | Human | | 表达系统 | Human cells | | Accession# | P01833 | | Source | Human Cells | | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 20mM Tris, 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 | PIGR binds polymeric IgA and IgM at the basolateral surface of epithelial cells. The complex is then transported across the cell to be secreted at the apical surface. During this process a cleavage occurs that separates the extracellular (known as the secretory component) from the transmembrane segment. |
