IL-2 antibody | AbD21766
Recombinant bovine interleukin-2 detected using Human anti Bovine interleukin-2, clone AbD21766 (HCA267) as the capture antibody and Human anti Bovine interleukin-2 clone AbD22297 (HCA268) followed by Mouse anti Histidine Tag:HRP (MCA1396P) as the detection reagent.
PBMC from naturally Mycobacterium bovis infected cattle were stained using Human anti Bovine interleukin-2 antibody, clone AbD21766, conjugated with Alexa Fluor 647 (HCA267A467) at a dilution of 1:8.

Antibody Quality and 
Unrivaled 
| Human anti Bovine Interleukin-2, clone AbD21766 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 AbD21766, has been successfully used for the detection and measurement of native and recombinant bovine IL-2 using intracellular flow cytometry, ELISPOT and ELISA. In ELISA and ELISPOT clone AbD21766 functions as the capture antibody in a sensitive assay for bovine IL-2 determination. |
