Ephrin-B1 Protein, Mouse, Reco

蛋白长度：A DNA sequence encoding the mouse EFNB1 (NP_034240.1) extracellular domain (Met 1-Ser 229) was expressed, fused with a polyhistidine tag at the C-terminus.

性质：

表达系统：HEK293 Cells

种属：Mouse

氨基酸序：Met1-Ser229

标签类型：C-His

分子量：The secreted recombinant mouse EFNB1 consists of 211 amino acids and has a predicted molecular mass of 23.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rmEFNB1 is approximately 33-38 kDa due to glycosylation.

活性：Measured by its ability to compete with mouse EphrinB1 / Fc for binding to immobilized mouse EphB3 in a functional ELISA assay.

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

基因名称：ephrin-B1

通用名：EFNB1

蛋白序参考：NP_034240.1

总结：Ephrin-B1 also known as EFNB1, is a member of the ephrin family. The transmembrane- associated ephrin ligands and their Eph family of receptor tyrosine kinases are expressed by cells of the SVZ. Eph/ephrin interactions are implicated in axon guidance, neural crest cell migration, establishment of segmental boundaries, and formation of angiogenic capillary plexi. Eph receptors and ephrins are divided into two subclasses, A and B, based on binding specificities. Ephrin subclasses are further distinguished by their mode of attachment to the plasma membrane: ephrin-A ligands bind EphA receptors and are anchored to the plasma membrane via a glycosylphosphatidylinositol (GPI) linkage, whereas ephrin-B ligands bind EphB receptors and are anchored via a transmembrane domain. An exception is the EphA4 receptor, which binds both subclasses of ephrins. EphrinB1 and B class Eph receptors provide positional cues required for the normal morphogenesis of skeletal elements. Another malformation, preaxial polydactyly, was exclusively seen in heterozygous females in which expression of the X-linked ephrinB1 gene was mosaic, so that ectopic EphB-ephrinB1 interactions led to restricted cell movements and the bifurcation of digital rays.

形式：Lyophilized

纯度：> 95 % 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.
