Description

Viscotoxin CAS NO 76822-96-3 is a potent, low-molecular-weight protein toxin derived from the European mistletoe (*Viscum album*). This compound is of significant interest due to its cytotoxic properties and its role in modulating immune responses. It is primarily utilized by researchers and developers in the pharmaceutical and biotechnology sectors for investigating novel cancer therapeutics and immunomodulatory agents.

Application

• Pharmaceutical Research: Serves as a key reference standard and active pharmaceutical ingredient (API) in the development of anti-cancer drugs and immunotherapies.
• Biochemical Studies: Used to study mechanisms of apoptosis (programmed cell death) and membrane pore formation in cell biology research.
• Immunology: Employed in research focused on natural killer (NK) cell activation and other immune system modulation effects.
• Quality Control: Acts as a critical standard for the identification and quantification of viscotoxins in mistletoe extracts and related botanical preparations.
• Preclinical Development: Utilized in *in vitro* and *in vivo* studies to assess efficacy, toxicity, and pharmacokinetic profiles of new therapeutic candidates.
