Cell Cytotoxicity Assay Services

 Cytotoxicity Assays are widely used by researchers and by the pharmaceutical industry to investigate the toxicity of compounds on cellular systems. Cytotoxicity assays provide a rapid, sensitive and validated approach to quantify harmful-dose ranges of compounds and to analyze the biological effects of toxicity on living cellular systems. Additionally, cytotoxicity testing can be used for quality control purposes for lot release testing of raw materials or of manufactured drug products.

Cell Cytotoxicity Assay

Medicilon can offer multiple readouts for quantifying the cytotoxicity of compounds, including colorimetric, fluorescent and luminescent assays that can be multiplexed with apoptosis or viability measurements. Our wide range of testing platforms includes the MultiTox-Glo Multiplex Cytotoxicity Assay and the ApoGlow, MTT, XTT, MTS, and LDH assays.

Available Cytotoxicity Assay:

Agarose Overlay
MEM Elution
Direct Contact Cytotoxicity
Indirect Contact Agar Diffusion Test
MTT Assay (quantitative)

In Vitro Toxicity Screening Services

In vitro testing using primary cells can quickly screen for new chemical entities with serious toxicology consequences. Using primary cells derived from human tissues, the relative risk can be determined in multiple organs over a population of donors. The following in vitro cytotoxicity assays using the specified endpoints have been developed in our laboratory. With our ready inventory of human and cynomolgus monkey, cells scheduling is not an issue. Contact IVAL to begin designing your study today.

Cell viability (luminescence based ATP assay)
Cell growth and survival (MTT/WST-1 metabolism)
Apoptosis
Oxidative Stress

Cytotoxicity is typically defined as the loss of membrane integrity as measured by membrane-impermeable dye uptake or the release of intracellular enzymes into the extracellular media. Promega offers multiple readouts for quantifying cytotoxicity.

Cytotoxicity assays

1.CytoTox-Glo Cytotoxicity Assay

The CytoTox-Glo Assay is the most sensitive method available for measuring cytotoxicity. The assay quantifies the extracellular activity of an intracellular protease (dead-cell protease) when the protease is released from membranecompromised cells. The amount of luminescence directly correlates with the percentage of cells undergoing cytotoxic stress.

2.CytoTox 96 Non-Radioactive Cytotoxicity Assay

The CytoTox 96 Assay is a colorimetric alternative to 51Cr release cytotoxicity assays. The CytoTox 96 Assay quantitatively measures lactate dehydrogenase (LDH),a stable cytosolic enzyme that is released upon cell lysis, in much the same way as 51Cr is released in radioactive assays.

3.CytoTox-ONE Homogeneous Membrane Integrity Assay
The CytoTox-ONE Assay is a fluorescent method to rapidly measure the activity of lactate dehydrogenase (LDH) released into the culture medium from cells with damaged cell membranes (non-viable cells). The amount of fluorescent product produced is proportional to the number of dead cells present.

What We Have:

Complete range of Cytoxicity markers
Single and multiple parameters from 1 cellular sample
High throughput screening methods
Easy handling, less hands-on time

Reduced amount of test compound and cells with the multiple parameter test kits

Medicilon and Binhui Biopharmaceutical Have Reached a Strategic Collaboration to Jointly Draw a New Blueprint for the Development of New Biological Drugs

  On March 18, Medicilon and Binhui Biopharmaceutical (Binui Bio) announced a strategic collaboration.  The two parties will work together to jointly explore the possibilities in cutting-edge fields such as oncolytic viruses, nucleic acid drugs and protein drugs. Gather and Work Together to Create Advantages      Facilitate the Research and Development of Oncolytic Viruses, Nucleic Acids, Proteins and Other Drugs As a one-stop biopharmaceutical comprehensive preclinical R&D service CRO, Medicilon has been developing and accumulating for 20 years, always adhering to the spirit of innovation, and has successfully constructed bi/multi-specific antibodies,  ADCs ,  mRNA vaccines ,  small nucleic acid drugs ,  PROTAC , and  CGT technical service platform  that have helped 421 INDs obtain clinical approval.  It is this outstanding achievement that has earned Medicilon wide recognition in the industry and laid a solid foundation f...

A Nickel-Catalyzed Reductive Alkylation of Aryl Bromides and Chlorides for Sp3-Sp2 Bond Formation

  In 2012, a nickel-catalyzed reductive alkylation method of aryl bromides and chlorides was reported. Under the optimized conditions, a variety of aryl and vinyl bromides as well as active aryl chloride can be reductively coupled with alkyl bromides in high yields. The protocols were highly functional-group tolerant and the reactions were not air or moisture sensitive. The reaction showed different chemoselectivity than conventional cross-coupling reactions. Substrates bearing both anelectrophilic and nucleophilic carbon resulted in selective coupling at the electrophilic carbon (R-X) and no reaction occurred at the nucleophilic carbon (R-[M]). The 2010 Nobel Prize in Chemistry was awarded for the Pd-catalyzed cross-coupling, and in the past decade the progress in cross-coupling has not only had a significant impact on academic research but has also influenced the industrial synthetic application. The transition-metal-catalyzed union of nucleophilic organo-boronic acids with elect...

What is Toxicokinetics?

Toxicokinetics  is essentially the study of “how a substance gets into the body and what happens to it in the body”. Four processes are involved in toxicokinetics. The study of the kinetics (movement) of chemicals was originally conducted with pharmaceuticals and thus the term pharmacokinetics became commonly used. In addition, toxicology studies were initially conducted with drugs. However, the science of toxicology has evolved to include environmental and occupational chemicals as well as drugs. Toxicokinetics is thus the appropriate term for the study of the kinetics of all toxic substances. Frequently the terms  toxicokinetics ,  pharmacokinetics , or disposition may be found in the literature to have the same meaning. Disposition is often used in place of toxicokinetics to describe the time-course of movement of chemicals through the body (that is, how does the body dispose of a xenobiotic?). The disposition of a toxicant along with its’ biological reactivi...
