Interleukin-9 Human Recombinant, HEK

Description	IL-9 Human Recombinant produced in HEK cells is a glycosylated monomer, having a molecular weight range of 38-48kDa due to glycosylation. The IL9 is purified by proprietary chromatographic techniques.
Synonyms	P40, HP40, T-cell growth factor p40, IL-9, P40 cytokine.
Source	HEK.
Purity	>96% as determined by SDS-PAGE and HPLC
Formulation	Sterile Filtered White lyophilized (freeze-dried) powder. The IL9 was lyophilized from 1mg/ml in 1xPBS.
Stability	The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity	The specific activity was determined by the dose-dependent stimulation of the proliferation of human MO7e cells (human megakaryoblastic leukemia cell line) and is typically 0.03-0.2ng/ml.
Solubility	It is recommended to reconstitute the lyophilized IL-9 in sterile water not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Usage	LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
