Description
Specificity:
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.
Background:
Interleukin-2 (IL-2) is a potent T-cell mitogenic cytokine1 that functions as a primary regulator of T cell homeostasis and has been considered a prime candidate immunotherapeutics, both for increasing T cell levels/function and for augmenting vaccine-elicited viral-specific T cell responses.2 IL-2 plays a key role in setting the balance between immunity and tolerance. This cytokine has a dual role as the regulator of the two main phases of the immune response (proliferative and suppressive).3 IL-2 also stimulates growth and differentiation of B cells, NK cells, LAK cells, monocytes, and oligodendrocytes.
Known Species Cross Reactivity: Hu+
Immunogen
Purified Recombinant Human IL-2 (>98%)
Formulation
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.
Reconstitution
We suggest aseptically reconstituting this biotinylated, lyophilized, antigen affinity purified polyclonal antibody with 1 ml of sterile 20 mM Trizma base, 0.15 M sodium chloride (1X Tris Buffered Saline) pH 7.2-7.3, containing 0.1% w/v bovine serum albumin (BSA). This will result in a final biotinylated antibody concentration of 50 µg/ml.
Storage and Stability
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 bioin 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.
Reported Applications
ELISA Det, WB, , ICC
Western Blotting: To detect Human IL-2 this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as UltraAvidin™- Horseradish Peroxidase (HRPO) (Leinco Prod. No.: A106) and a chromogenic substrate such as TMB HRPO Membrane/IHC Substrate UltraSensitive™ One Component "Ready Use" (Leinco Prod. No.: T343). The detection limit for Human IL-2 is 2 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used. A suitable Western blotting control is Recombinant Human IL-2 (Leinco Prod. No.: I-184).
ELISA Sandwich Assay: This antibody can be used as the detection antibody in a sandwich ELISA at a concentration of approximately 0.1-0.4 µg/ml when used in conjunction with Anti-Human IL-2 (Leinco Prod. No.: I-685) as the capture antibody at 2 - 8 µg/ml and an optimal second step reagent such as UltraAvidin™- Horseradish Peroxidase (HRPO) (Leinco Prod. No.: A106) for the detection of Human IL-2.
Immunocytochemistry: This antibody will detect IL-2 in cells. The working dilution is 5 - 15 μg/mL.
