Relevance

High-affinity receptor for interleukin-15. Can signal both in cis and trans where IL15R from one subset of cells presents IL15 to neighboring IL2RG-expressing cells. In neutrophils, binds and activates kinase SYK in response to IL15 stimulation. In neutrophils, required for IL15-induced phagocytosis in a SYK-dependent manner. Expression of different isoforms may alter or interfere with signal transduction.

Endotoxin

Less than 1.0 EU/μg as determined by LAL method.

Purity

Greater than 95% as determined by SDS-PAGE.

Activity

Yes

Bioactivity

Measured by its binding ability in a functional ELISA. Immobilized Human IL15RA at 2 μg/mL can bind Human IL15 (CSB-MP011593HU) .The EC50 is 32.53-38.41 ng/mL.

Form

Lyophilized powder

Buffer

Lyophilized from a 0.2 μm sterile filtered PBS, 6% Trehalose, pH 7.4

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Conditions

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
