| Human anti Bovine Interleukin-2, clone AbD22297 recognizes bovine interleukin-2 (IL-2), also known as T-cell growth factor (TCGF). Bovine IL-2 is a 155 amino acid secreted cytokine produced by T-cells following antigenic or mitogenic stimulation. It plays a crucial role in T-cell proliferation and immune regulation. Human anti bovine interleukin-2, clone AbD22297, has been successfully used for the detection and measurement of native and recombinant bovine IL-2 in ELISA where it acts as the detection antibody in a sensitive assay for bovine IL-2 determination. Bio-Rad recommend clone AbD21766 (HCA267) for intracellular flow cytometry. |
- Target Species
- Bovine
- Product Form
- A bivalent human recombinant Fab (kappa light chain) selected from the HuCAL® phage display library, expressed in E. coli. This Fab fragment is bivalent by dimerization of the bacterial alkaline phosphatase fusion protein. The antibody is tagged with a V5 tag and a double extended Strep-tag (SAWSHPQFEKGGGSGGGSGGSAWSHPQFEK).
- Preparation
- Metal chelate affinity chromatography
- Buffer Solution
- Phosphate buffered saline
- Preservative Stabilisers
- 0.01% Thiomersal
- Immunogen
- Fc-fusion protein containing the amino acid sequence 21-155 from bovine interleukin-2
- Affinity
- The monovalent intrinsic affinity of this antibody was measured as KD=0.3 nM by real time, label-free molecular interaction analysis on recombinant bovine IL-2.
- Approx. Protein Concentrations
- Antibody concentration 0.5 mg/ml
- Regulatory
- For research purposes only
- Guarantee
