Form/Format
Lyophilized from sterile PBS, pH7.4.
Protein Length
The recombinant Human IL-4 protein consists of 133 amino acids and has a predicted molecular mass of 15.4kDa. The apparent molecular mass of the Human IL-4 protein is approximately 18kDa in SDS-PAGE under reducing conditions.
Reconstitution
Use the buffer we provided to reconstitute the lyophilized Human IL-4 protein
Endotoxin
< 1 EU per ug of the protein as determined by the LAL method
Usage Notes
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 ug/mL, which can then be further diluted to other aqueous solutions.
Preparation and Storage
Lyophilized Human IL-4 proteinshould be stored desiccated below -20 degree C. Upon reconstitution, the protein should be Store at 4 degree C between 2-7 days and for future use below -20 degree C. For long term storage it is recommended to add a carrier protein (0.129% HSA or BSA). Please prevent freeze-thaw cycles.

Related Product Information for IL-4 recombinant protein
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.

Product Notes
The IL-4 il4 (Catalog #AAA332527) is a Recombinant Protein produced from HEK293 Cells and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "IL-4, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
