存储及稳定性：在接收后，该产品在低于-70°C的环境下保持稳定长达6个月。重组后，产品应在4°C下稳定1周或在-20°C下稳定3个月。为了长期保存，建议添加载体蛋白(如0.1% BSA)。避免反复的冻融循环。
生物活性:粒细胞巨噬细胞集落刺激因子(GM-CSF)最初被认为是一种能够支持粒细胞-巨噬细胞祖细胞体外集落形成的生长因子。粒细胞巨噬细胞集落刺激因子(GM-CSF)由许多不同类型的细胞产生，包括活化的T细胞、B细胞、巨噬细胞、肥大细胞、内皮细胞和成纤维细胞，对免疫和炎症刺激的细胞因子做出反应。此外，粒细胞巨噬细胞集落刺激因子(GM-CSF)可以刺激多种肿瘤细胞系的增殖，包括骨肉瘤、癌和腺癌细胞系。

| Recombinant Human Serpin A12 (E.coli, N-GST)
Vaspin (Visceral Adipose-Specific SERPIN) is a newly described adipokine. Vaspin is also a unique insulin sensitizing adipocytokine in obesity. |
| Recombinant Human B2M Protein (Mammalian, C-6His)
β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states. |
| Recombinant Mouse E-Selectin/CD62E Protein (HEK293)
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. |
