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.≥95%(SDS-PAGE)See COA

Reconstitución
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute at 1.0 mg/mL in 20mM HAc-NaAc, 0.004% Tween 80, pH 4.0. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Recombinant Human IL-2 Protein (rp228980) - Protein Bioactivity
Measured in a cell proliferation assay using mouse splenocytes. The ED₅₀ for this effect is typically 38.0 ng/mL.
Recombinant Human IL-2 Protein (rp228980) - SDS-PAGE
3 μg/lane of Recombinant Human IL-2 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 16.0 & 31.1 kDa under reducing conditions and 16.0 & 30.5-31.9 & 46.2 kDa under non-reducing conditions.
The presence of intermolecular disulfide bonds in the IL-2 protein is likely the primary reason for aggregate formation (Uniprot ID: P60568).
