基质细胞衍生因子-1β (SDF-1β)，也被称为SCYB12, PBSF和CXCL12，是一个8.3 kDa，肝素结合的CXC(或α)趋化因子家族成员，通过CXCR4受体发出信号。据报道，SDF-1α和β在中性pH和生理离子强度下是单体。在细胞表面，这可能很好地促进了SDF-1与其两个受体CXCR4和syndecan4的相互作用。已知硫酸肝素可以保护SDF-1不被蛋白质水解，CXCR4作为二聚体组成存在。在其众多功能中，已知CXCL12影响淋巴生成，调节神经祖细胞的模式和细胞数量，并促进血管生成(12,13)。它还能增强髓样祖细胞的存活。

E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis. |
| Recombinant Human DPP4/CD26 (Mammalian, C-6His)
DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. |
| Recombinant Human USP14 (E.coli, N-6His)
USP14 belongs to the ubiquitin-specific processing (USP) family which is a deubiquitinating enzyme (DUB) with His and Cys domains. USP14 acts also as a physiological inhibitor of endoplasmic reticulum-associated degradation (ERAD) under the non-stressed condition by inhibiting the degradation of unfolded endoplasmic reticulum proteins via interaction with ERN1. |
