Bovine IL21

Rabbit

Bovine, Horse, Pig (tested or 100% immunogen sequence identity)

Horse, Pig (at least 90% immunogen sequence identity)

IgG Polyclonal

Unconjugated

Protein A affinity chromatography

Lyophilized

This protein-A purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a recombinant protein raised in yeast, corresponding to amino acid residues 24-152 of bovine IL-21 protein.

aa24-152

This antibody is specific for bovine IL-21 protein. A BLAST analysis was used to suggest cross-reactivity with IL-21 from bovine sources based on 100% homology with the immunizing sequence. Based on 92% homology, there is a chance of cross-reactivity to porcine IL- 21, 91% to horse IL-21, 89% to human and dog, 88% to macaque, 84% to platypus and Syrian hamster, 76-79% to mouse, 75% to rat, and 48% to chicken. Cross-reactivity with IL-21 from other sources has not been determined.

• Western blot (1 µg/ml)
• ELISA (1:6000)

IL-21 is expressed in activated CD4-positive T-cells but not in CD8-positive T-cells, B-cells, or monocytes, and in HL-60 and THP-1 cell lines. This protein-A purified antibody has been tested for use in ELISA and western blotting. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 15.1 kD in size corresponding to bovine IL-21 protein by western blotting in the appropriate cell lysate or extract.
