Purity: ≥95 % as determined by SDS-PAGE
Formulation: Lyophilized from sterile PBS, pH 7.4.
Kit Component: N/A
Features & Benefits : N/A
Molecular Weight: 15.4 kDa
Usage Note: Always centrifuge tubes before opening. It is recommended to reconstitute the lyophilized Human IL-4 protein using the buffer we provided not less than 100 µg/mL, which can then be further diluted to other aqueous solutions.
Storage Conditions: Lyophilized Human IL-4 proteinshould be stored desiccated below -20°C. Upon reconstitution, the protein should be stored at 4°C between 2-7 days and for future use below -20°C. For long term storage it is recommended to add a carrier protein (0.129% HSA or BSA) . Please prevent freeze-thaw cycles.
Shipping: The product is shipped at ambient temperature.
Background: Interleukin-4 (IL-4), an anti-inflammatory cytokine, plays significant role in pathogenesis of various diseases such as asthma, tumors, and HIV infections. IL-4 is firstly identified as a T cell-derived growth factor for B cells. IL-4 can mediate important pro-inflammatory functions in asthma, including T helper cell type 2 lymphocyte differentiation, induction of IgE production, up-regulation of IgE receptors, expression of vascular cell-adhesion molecule 1, promotion of eosinophil transmigration into the lungs, inhibition of T-lymphocyte apoptosis, and mucus hypersecretion. The role of IL-4 in the pathogenesis of asthma is supported by identification of polymorphisms linked to asthma in the IL-4 gene promoter and proteins involved in IL-4 signaling.
