GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.High Performance?High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.PBS Only?PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers.≥95%(SDS-PAGE)See COA

Biochemical and Physiological Mechanisms
The protein encoded by the IL15 gene is a cytokine that regulates T and natural killer cell activation and proliferation. This cytokine and interleukine 2 share many biological activities. They are found to bind common hematopoietic receptor subunits and

Recombinant Human IL-15 Protein (rp215091) - Protein Bioactivity
Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED₅₀for this effect is typically 0.38 ng/mL.
Recombinant Human IL-15 Protein (rp215091) - Binding Activity Immobilized Recombinant Mouse IL-15R alpha Protein (rp168266) at 2.0 μg/mL can bind Recombinant Human IL-15 Protein (rp215091) with the EC₅₀ of 115.0 ng/mL.
Recombinant Human IL-15 Protein (rp215091) - SDS-PAGE 3 μg/lane of Recombinant Human IL-15 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 80.0-92.0 kDa under reducing conditions and 68.0-80.0 kDa under non-reducing conditions. The protein as both dimers and monomers under non-reducing (NR) conditions suggests that a portion of the protein forms dimers. This dimerization may be mediated by (or stabilized by) disulfide bonds (Uniprot：P40933).
