Biological Activity

Genus: Mouse
Expression system: E. coli
Purity: >95% by SDS-PAGE analysis
Endotoxin: < 0.2 EU/μg of protein by gel coagulation
Apparent molecular weight: ~15.2 kDa on SDS-PAGE under non-reducing conditions
Storage and Stability: This product is stable for up to 6 months at temperatures below -70°C after receipt. After reconstitution, the product should be stable for 1 week at 4°C or for 3 months at -20°C. For long-term storage, the addition of a carrier protein (e.g. 0.1% BSA) is recommended. Avoid repeated freeze-thaw cycles.


Bioactivity: Interleukin-3 (IL-3) is a polymorphic cytokine belonging to the interleukin family.IL-3 shares similarities with granulocyte-macrophage colony-stimulating factor (GM-CSF) and IL-5: they both have a four-helix bundle structure, are located on the same chromosome in both humans and mice, are produced by activated T cells, and have a common receptor.IL- IL-3 is also known as a multicolony stimulating factor because it stimulates the development and colony formation of multilineage hematopoietic cells by activating intracellular pathways such as Ras-Raf-ERK and JAK/STAT. -2 gene family to inhibit apoptosis and promote cell survival.

Chemical Information
Solubility (25°C) It is recommended that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute the lyophilized powder in ddH₂O up to 100 μg/ml.
Storage Powder          -20°C   3 years ;  4°C   2 years
In solvent       -80°C   6 months ;  -20°C   1 month

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.

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.
