Human IL-5 ELISA kits

Pick the right ELISA kit for Human IL-5. Our kits differ in what we put in the box and how you develop the signal – this page explains what those differences mean.

IL-5 ELISA kits are also available for bovine, goat, mouse, porcine, and sheep.

What differs between these kits

Whether a pre-coated plate is included

Some of our kits arrive with the plate already coated with the capture antibody, so you can start with your samples. Others supply the antibodies and standard only. Coating your own plate is more work, and it gives you control over the coating conditions and the plate.

Which detection system

Available with Streptavidin-ALP or Streptavidin-HRP. You add the streptavidin conjugate as a second incubation after the biotinylated antibody, which amplifies the signal. Alkaline phosphatase (ALP) and horseradish peroxidase (HRP) perform equivalently, so that choice usually comes down to the substrate and reader you already work with.

Supplied without a plate, streptavidin conjugate

With a pre-coated strip plate, streptavidin conjugate, 1 plate

With a pre-coated strip plate, streptavidin conjugate, 2 plates

With a pre-coated strip plate, streptavidin conjugate, 10 plates

About IL-5

These Human IL-5 ELISA kits target IL5 (Homo sapiens, Gene ID 3567).

Interleukin 5 (IL-5) is a pleiotropic cytokine primarily produced by T and NK cells. IL-5 specifically controls the survival, differentiation, and chemotaxis of eosinophils. But initially, IL-5 was characterized by its ability to support the growth and terminal differentiation of B cells.
