Anti-Human IL-2 – Biotin

Purified Recombinant Human IL-2 (Accession # P60568)

This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted biotin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Immunocytochemistry: Suitable for use at concentration of 5-15 µg/mL.

Goat Anti-Human Interleukin-2 (IL-2) recognizes Human IL-2. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

IL-2 is a 17.2 kD cytokine signaling protein that is the regulator of the proliferative and suppressive phases of the immune response, and stimulates growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes. It functions as a primary regulator of T cell homeostasis. Il-2 regulates the activities of white blood cells and plays a role in the immune system via “self” and “non-self” discrimination. IL-2 is a prime candidate in immunotherapeutics for both increasing T cell levels/function and for augmenting vaccine-elicited viral-specific T cell responses. IL-2 signal can be transduced via 3 different signaling pathways that include the JAK-STAT, PI3K/Akt/mTOR and MAPK/ERK pathways. Aldesleukin is a form of recombinant interleukin-2 for the treatment of cancers including malignant melanoma and renal cell cancer. Furthermore, there is additional therapeutic potential for IL-2 mAb use with transplants and autoimmune disease.
