General description

Interleukin-1α (IL-1α) is a cytokine that belongs to the interleukin-1 (IL-1) family. It is located intracellularly in hematopoietic and non-hematopoietic cells. IL-1α gene is located on the human chromosome at 2q14.1.

Application

Interleukin-1α (IL-1α) has been used:
  • to study its effects on human colorectal adenocarcinoma cells
  • to stimulate primary human fetal retinal pigment epithelium (hfRPE) cells
  • to pre-stimulate human THP-1 monocytes

Biochem/physiol Actions

Interleukin-1α (IL-1α) plays a crucial role in inflammation during cell necrosis. It also regulates the recruitment of interleukin-1β (IL-1β), neutrophils, chemokines, and other cytokines at the site of injury. IL-1α exhibits a dual function of binding to its cell surface receptor as well as chromatin.

Physical form

Lyophilized from 0.2 μm filtered 10 mM sodium phosphate , pH 8.0, plus 50 mm NaCl and 50 μg bovine serum albumin (BSA) per μg cytokine.

Analysis Note

The proliferative activity of human IL-1α is tested in culture using the murine cell line D10S.
