IL-2 is a potent lymphoid cell growth factor which exerts its biological activity primarily on T cells promoting proliferation and maturation. Additionally, IL-2 has been found to stimulate growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes.
Product DetailsProduct Details
- Source
- Human IL-2, Ala 21 - Thr 153 - Accession Number NM_000586, was expressed in E. coli.
- Molecular Mass
- The 133 amino acid recombinant protein has a predicted molecular mass of 15,418 Da. The DTT-reduced and non-reduced protein migrates at approximately 13kDa by SDS-PAGE. The N-terminal amino acid is Ala.
- Purity
- Purity is >98% as determined by SDS PAGE of 6 µg of reduced and non-reduced recombinant human IL-2.
- Formulation
- Lyophilized in sterile-filtered PBS, pH 7.2, containing 1% BSA, 0.09% sodium azide, and protease inhibitors.
- Concentration
- Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)
- Storage & Handling
- Unopened vials can be stored between 2°C and 8°C until the expiration date. Prior to use, reconstitute the lyophilized powder with 0.2 mL of PBS containing a carrier protein (e.g., 1% BSA, protease free), pH7.4. Re-cap vial, vortex. Allow the reconstituted standard to sit at room temperature for 15 minutes, vortex again to mix completely. The reconstituted standard stock solution can be aliquoted into polypropylene vials and stored at -70°C for up to one month. Do not re-use diluted standards. Avoid repeated freeze/thaw cycles.
- Application
-
ELISA
- Recommended Usage
-
Each lot of this protein is quality control tested by ELISA assay. For use as an ELISA standard, a standard curve comprised of doubling dilutions from 2000 pg/ml to 15 pg/ml is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
-
This IL-2 protein is useful as a standard for a human IL-2 sandwich ELISA, using unlabeled MQ1-17H12 antibody (catalog #500302) for capture and biotinylated Poly5176 antibody (catalog #517605) for detection.
