CADM1 Protein, Human, Recombin

蛋白长度：A DNA sequence encoding the human CADM1 (NP_055148.3) extracellular domain (Met 1-His 374) was expressed, fused with a polyhistidine tag at the C-terminus.

性质：

表达系统：HEK293 Cells

种属：Human

氨基酸序：Met1-His374

标签类型：C-His

分子量：The secreted recombinant human CADM1 consists of 341 amino acids after removal of the signal peptide and has a predicted molecular mass of 38.5 kDa. As a result of glycosylation, the apparent molecular masss of rh CADM1 is approximately 70-80 kDa in SDS-PAGE under reducing conditions.

活性：Measured by its binding ability in a functional ELISA. Immobilized recombinant human CADM1 at 2 μg/ml (100 μl/well) can bind biotinylated human CRTAM with a linear range of 12.5-400 ng/ml.

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.

基因名称：cell adhesion molecule 1

通用名：CADM1

蛋白序参考：NP_055148.3

总结：Members of the immunoglobulin superfamily often play key roles in intercellular adhesion. IGSF4 is a novel immunoglobulin (Ig)-like intercellular adhesion molecule. Three Ig-like domains are included in the extracellular domain of IGSF4 and mediate homophilic or heterophilic interactions independently of Ca2+. The cytoplasmic domain of IGSF4 contains the binding motifs that connect to actin fibers. Since IGSF4 has been characterized by several independent research groups, this molecule is called by three names, TSLC1, SgIGSF and SynCAM. IGSF4 was first characterized as a tumor suppressor of non-small cell lung cancer and termed TSLC1. It is a single-pass type I membrane protein which belongs to the nectin family, which may be involved in neuronal migration, axon growth, pathfinding, and fasciculation on the axons of differentiating neurons. In addition, CADM1 may play diverse roles in the spermatogenesis including in the adhesion of spermatocytes and spermatids to Sertoli cells and for their normal differentiation into mature spermatozoa. In neuroblastoma, loss of CADM1 expression has recently been found in disseminated tumours with adverse outcome, prompting us to investigate its role in neuroblastoma tumour progression. The downregulation of CADM1 tumour suppressor gene expression is a critical event in neuroblastoma pathogenesis resulting in tumour progression.

形式：Lyophilized

纯度：> 94 % as determined by SDS-PAGE.

储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.

储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
