产品名称:Human CD89 Protein

别名: IgA Fc receptor、Immunoglobulin alpha Fc receptor、CD89

背景说明: CD89 (Fc alphaRI) is the human myeloid IgA Fc receptor expressed on cells, such as neutrophils, eosinophils and monocytes/macrophages.CD89 is a transmembrane glycoprotein that binds both subclasses of IgA in all its molecular forms (i.e. monomeric, dimeric and secretory IgA) via a region of its membrane-distal EC1 domain.

序列: Met 1-Asn 227

Accession: NP_001991.1

种属: Human

来源: Recombinant Human CD89 Protein is expressed from Expi293 with a His Tag at the C-terminal.;It contains Met 1-Asn 227.

分子量: The protein has a predicted MW of 24.6 kDa.Due to glycosylation, the protein migrates to 45-65 KDa based on Bis-Tris PAGE result.

纯度: > 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC

内毒素水平: Less than 1 EU per μg by the LAL method.

形态: Lyophilized from 0.22um filtered solution in PBS (pH 7.4).Normally 5 % trehalose is added as protectant before lyophilization.

储存/保存方法: The product should be stored at -70℃ or -20℃.
