IONOMYCIN CALCIUM SALT

Description

Ionomycin is a calcium ionophore originally isolated from S. conglobatus. It induces intracellular calcium mobilization in X. laevis oocytes when used at a concentration of 5 μM. Ionomycin (5 μM) induces the formation of neutrophil extracellular traps (NETs) in isolated human neutrophils. Ionomycin in combination with phorbol 12-myristate 13-acetate (PMA; ) has commonly been used to induce the proliferation and activation of T cells, as well as to stimulate cytokine production in macrophages, in vitro.

The Uses of IONOMYCIN CALCIUM SALT

Ionomycin calcium salt is used as a polyether antibiotic and apoptotic degeneration inducer. Ionomycin induces apoptotic degeneration of embryonic cortical neurons and cell cycle arrest at G1 phase. It is more effective than A23187 (sc-3591) and provides a useful tool for increasing intracellular Ca2+ concentration.

The Uses of IONOMYCIN CALCIUM SALT

Ionomycin is more effectivethan A23187 as a Ca++ionophore; Ionomycin is used in research on Ca++ transport across biological membranes; Ionomycin induces apoptotic degeneration of embryonic cortical neurons.

What are the applications of Application

Ionomycin calcium salt (1 mM solution in DMSO) is a selective ionophore and an ion carrier for Ca2+.

What are the applications of Application

Ionomycin is a reversible ion binding calcium ionophore, polyether antibiotic, and apoptotic degeneration inducer

General Description

Useful in cell activation experiments when calcium dose-response data are not required. Also available as a 10 mM solution in DMSO (Cat. No. 407953).

Biological Activity

Calcium ionophore; more specific than A23187 (5-(Methylamino)-2-[[2R,3R,6S,8S,9R,11R)-3,9,11-trimethyl-8-[(1S)-1-methyl-2-oxo-2-(1H-pyrrol-2-yl)-ethyl]-1,7-dioxaspiro[5.5]undec-2-yl]methyl]-4-benzoxazolecarboxylic acid ).
