Product Introduction

Bioactivity

Bioactivity	Measured in a cell proliferation assay using CTLL‑2 mouse cytotoxic T cells. The ED50 for this effect is 0.4 - 1 ng/ml (QC Test).
Description	IL-2 Protein, Mouse, Recombinant (HEK293) is expressed in HEK293 Cells. The accession number is P04351-1.
Species	Mouse
Expression System	HEK293 Cells
Tag	Tag Free
Accession Number	P04351-1
Construction	Ala21-Gln169
Protein Purity	> 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
Endotoxin	< 1 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Synonyms	TCGF, T-cell growth factor, interleukin 2, Il-2, IL-2, IL2, IL 2, Aldesleukin
Research Background	Interleukin-2 (IL-2) is an interleukin, a type of cytokine signaling molecule in the immune system. It is a 15,5 - 16 kDa protein that regulates the activities of white blood cells (leukocytes, often lymphocytes) that are responsible for immunity. IL-2 has essential roles in key functions of the immune system, tolerance and immunity, primarily via its direct effects on T cells.

Chemical Properties

Molecular Weight	17.23 kDa (Predicted); 23-28 kDa (Reducing condition, due to glycosylation)

Storage & Solubility Information

Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
