Application

Verapamil hydrochloride has been used:
  • to inhibit calcium oscillation in fertilized oocyte
  • to block calcium channel, thereby blocking the action of IL-1β (interleukin-1β), resulting in membrane depolarization
  • to investigate the effect of verapamil on cytotoxicity of 1,3-dilinoleoylglycerol (DLG)

Biochem/physiol Actions

α1-adrenoceptor antagonist; L-type calcium channel blocker. Blocks L-type Ca2+ channels in smooth and cardiac muscle, induces apoptosis of human primary and metastatic colon adenocarcinoma cells in vitro. Drug resistance reversal agent acting on Pgp, e.g. decrease renal tubule elimination of digoxin. Increases basal ATPase activity of Pgp. Substrate of Cyp3A4 and CYP2C6.

Changes in intracellular calcium concentration ([Ca2+]i) in fertilized mouse oocytes were measured using the calcium-sensitive dye, fura-2. After fertilization, an initial long-lasting [Ca2+]i increase was followed by a periodic [Ca2+]i increase. The periodic increase in [Ca2+]i persisted for 1 to

The possibility that membrane depolarization of synovial fibroblasts caused by interleukin-1beta (IL-1beta) was mediated by protein kinase C (PKC) and Ca2+ influx was studied using inhibitor and activator analysis. The effect of IL-1beta was blocked by bisindolylmaleimide I, an inhibitor

Cancer Stem Cell Detection Utilizing a Red-shifted Fluorescent Live Cell Probe for Aldehyde Dehydrogenase (ALDH), AldeRed™ 588-A.

AldeRed™ 588-A is a red fluorescent live cell probe that detects ALDH activity used to identify cancer stem cells and progenitor cells in culture. Cancer stem cells (CSCs) are subpopulations of cancer cells that can self-renew, generate diverse cells in the tumor mass, and sustain tumorigenesis. Some researchers believe that cancer arises from cancer stem cells that originate as a result of mutational hits on normal stem cells.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
