重组小鼠SDF-1蛋白又称 CXCL12，是一种高度保守的小型趋化细胞因子（8 kDa），属于 CXC 趋化因子大家族。SDF-1 主要与 CXC 受体 4（CXCR4；CD184）结合。CXCL12 与 CXCR4 结合后，能通过几种不同的途径诱导细胞内信号传导，启动与趋化、细胞存活和/或增殖、细胞内钙增加和基因转录有关的信号。
别名：Stromal cell-derived factor 1; CXCL12
The stromal cell-derived factor-1 (SDF1), also known as CXCL12, is a small (8 kDa) cytokine highly conserved chemotactic cytokine belonging to the large family of CXC chemokines. SDF-1 binds primarily to CXC receptor 4 (CXCR4; CD184). The binding of CXCL12 to CXCR4 induces intracellular signaling through several divergent pathways initiating signals related to chemotaxis, cell survival and/or proliferation, increase in intracellular calcium, and gene transcription. SDF-1/CXCL12 has crucial roles in the formation of multiple organ systems during embryogenesis and in the regulation of bone marrow haematopoiesis and immune function in the postnatal organism.
A DNA sequence encoding the mature form of mouse SDF-1 (Lys22-Lys89) was expressed and purified with an initial Met.
The recombinant mouse SDF-1 consists of 69 amino acids and predicts a molecular mass of 8.1 KDa. It migrates as an approximately 8 KDa band in SDS-PAGE under reducing conditions.

| 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. |
| Recombinant Human EpCAM/Trop-1 (Mammalian, C-Fc)
Epithelial Cell Adhesion Molecule (EpCAM) is a signal type I transmembrane glycoprotein. EpCAM plays a role in embryonic stem cells proliferation and differentiation; it up-regulates the expression of FABP5, MYC and Cyclin A and Cyclin E. It is highly and selectively expressed by undifferentiated embryonic stem cells. |
