表達(dá)方式: 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
種屬: Mouse
表達(dá)宿主: Human Cells
EFNB1 / Ephrin-B1蛋白質(zhì)控指標(biāo)
純度: > 95% as determined by SDS-PAGE SDS-PAGE
生物活性:Measured by its ability to compete with mouse EphrinB1 / Fc for binding to immobilized mouse EphB3 in a functional ELISA assay
內(nèi)**: < 1.0 EU per μg of the protein as determined by the LAL method
穩(wěn)定性: Samples are stable for up to twelve months from date of receipt at -70℃
預(yù)測(cè)N端: Lys 30
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
緩沖液: Lyophilized from sterile PBS , pH 7.4
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Please contact us for any concerns or special requirements.
EFNB1 / Ephrin-B1蛋白使用指南
儲(chǔ)存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
EFNB1 / Ephrin-B1蛋白背景綜述
The ephrins (Eph) and Eph receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in developmental events, especially in the nervous system and in erythropoiesis. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. All ephrins share a conserved extracellular sequence, which most likely corresponds to the receptor-binding domain. In molecular biology, ephrins and Eph receptors are components of cell signaling pathways involved in animal development, and implicated in some cancers. Mouse ephrin-B1, also known as LERK-2, ELK-L, EFL-3, Cek5-L, and STRA-1, is a member of the ephrin ligand family which binds members of the Eph receptor family. Ephrin-B1 has been shown to bind EphA3, EphB1, EphB2, EphB3, and EphB4. The extracellular domains of human and mouse ephrin-B1 share 94% amino acid identity.
