ActoFactor™ Recombinant Mouse Interleukin 5

Cat.No.
CSC-CTK0684
Description
IL-5 is a hematopoietic growth factor that stimulates the proliferation and activation of eosinophils. Produced by mast cells, T cells, and eosinophils, IL-5 plays an important role in inducing cell-mediated immunity against parasitic infections and certain tumors. Elevated levels of IL-5 lead to Eosinophilia, which may result in the induction of asthma and other allergic diseases. Human and murine IL-5 is cross-species reactive. Recombinant murine IL-5 is a 26.2 kDa disulfide-linked homodimeric protein containing two 113 amino acid chains.
Species
Mouse
Product Overview
Mouse Il5 expressed in E.coli
Molecular Mass
26.2 kDa
Size
CAT# CSC-CTK0684-25 (25 μg); CAT# CSC-CTK0684-125 (125 μg)
Expression System
E.coli
Purity
Greater than 98% as determined by SDS-PAGE and HPLC analysis.
Activity
The ED50 as determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is 5 x 10^5units/mg.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered protein solution containing 10 mM Sodium Phosphate, pH 7.5.
Reconstitution
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
