重组人LIF蛋白（Recombinant Human LIF Protein）通过抑制胚胎干细胞的自发分化，促进胚胎干细胞的长期维持。
别名：Leukemia Inhibitory Factor
重组人LIF蛋白（Recombinant Human LIF Protein）通过抑制胚胎干细胞的自发分化，促进胚胎干细胞的长期维持。LIF是由多种细胞类型(包括T细胞、髓细胞系、成纤维细胞、肝脏、心脏和黑色素瘤)产生的一种多营养因子。人 LIF 在小鼠细胞上具有活性，被广泛应用于维持小鼠 ESC 的自发分化，而小鼠 LIF 由于不能与人 LIF 受体结合而不能在人细胞上发挥作用。
重组人LIF包含186个氨基酸，预测分子量为20.5kd。
基于刺激人TF-1细胞增殖的能力，预期ED50是≤0.1 ng/ml，对应活性为≥1×107 IU/mg。
内毒素 ≤0.01EU/ug

| 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. |
| Recombinant Human IL-36 gamma/IL-1 F9 Protein (E. coli, aa 18-169, His Tag)
The recombinant human IL1F9 consists of 168 amino acids and predicts a molecular mass of 19.1 KDa. A DNA sequence encoding the mature form of human IL1F9 (Ser18-Asp169) was expressed with a polyhistide tag at the N-terminus. |
| Recombinant Human IL-36 gamma/IL-1 F9 Protein (E. coli)
The recombinant human IL1F9 consisting of 169 amino acids and has a calculated molecular mass of 18.9 kDa. A DNA sequence encoding the human IL-1F9 isoform 1 (Met 1-Asp 169) was expressed. |
| Recombinant Human APOL1 Protein (Baculovirus-Insect, C-His)
APOL1, also known as apolipoprotein L1, belongs to the apolipoprotein L family. It may play a role in lipid exchange and transport throughout the body. |
