Description

IL21 antibody

Research Area

Immunology & Inflammation

Images & Validation

• Tested Applications: ELISA, WB
• Dilution Range: ELISA: 1:6,000, WB: 1 µg/mL
• Reactivity: Bovine, Equine, Porcine
• Application Notes:
  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 kDa in size corresponding to bovine IL-21 protein by western blotting in the appropriate cell lysate or extract.

Key Properties

• Antibody Type: Primary Antibody
• Host: Rabbit
• Clonality: Polyclonal
• Isotype: IgG
• Immunogen: 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.
• Target: IL21
• Purity: This product was Protein-A purified from monospecific antiserum by chromatography. 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.
• Conjugation: Unconjugated
