Catalog #: CYT-097
Description:
IL-4 Human Recombinant produced in HEK cells is a glycosylated monomer, having a molecular weight range of 14-19kDa due to glycosylation.
The IL-4 is purified by proprietary chromatographic techniques.
Synonyms:
BCGF, BCDF, B cell stimulating factor, BSF-1, Lymphocyte stimulatory factor 1, IL-4, MGC79402, Binetrakin, Pitrakinra.
Source:
HEK.
Purity:
Greater than 95% as obsereved by SDS-PAGE.
Solubility:
It is recommended to reconstitute the lyophilized IL-4 in sterile water not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
Formulation:
The IL4 was lyophilized from 1mg/ml in 1xPBS.
Stability:
Lyophilized IL-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution IL4 should be stored at 4 °C between 2-7 days and for future use below -18 °C.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Activity:
The activity was determined by the dose dependent stimulation of the proliferation of human TF-1 cells (human erythroleukemic indicator cell line) and is typically 0.1-0.5ng/ml.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
