Biological Activity

Species: Human
Expression system: E. coli
Purity: SDS-PAGE analysis, > 95%, HIGH performance liquid chromatography analysis, > 95%
Endotoxin: protein < 0.2 EU/μg was determined by gel coagulation
Apparent molecular weight: ~7.6 kDa, sdS-PAGE under reduction conditions
Storage and stability: After receiving, the product remains stable at temperatures below -70°C for up to 6 months. After recombination, the product should be stable at 4°C for 1 week or -20°C for 3 months. For long-term preservation, carrier protein (e.g. 0.1% BSA) is recommended. Avoid repeated freeze-thaw cycles


Bioactivity: The EC50 value of human MIP-1 β /CCL4 against Cho-K1 / Gα15/hCCR5 cells (in which human Gα15 and human CCR5 were stably expressed) was less than 100.0 ng/ mL. Mip-1 β is a major HIV suppressor produced by CD8+ T cells. Perforin-low Memory CD8+ T cells are the most common T cells that synthesize MIP-1 β in humans. Mip-1 β has been shown to interact with CCL3. It can signal through the CCR5 receptor.


Chemical Information

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

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.
