LC/MS Introduction

LC/MS is short for Liquid Chromatography / Mass Spectrometers.

Liquid Chromatography (LC) is a fundamental separation technique in the life sciences and related fields of chemistry. Unlike gas chromatography, which is unsuitable for nonvolatile and thermally fragile molecules, liquid chromatography can safely separate a very wide range of organic compounds, from small-molecule drug metabolites to peptides and proteins.

Mass Spectrometers (MS) also generate three dimensional data. In addition to signal strength, they generate mass spectral data that can provide valuable information about the molecular weight, structure, identity, quantity and purity of a sample. Mass spectral data add specificity that increases confidence in the results of both qualitative and quantitative analyses.

Why and When to Use LC/MS

The use of LC-MS in many application areas within analytical science continues to grow almost exponentially. Listed below are some pointers as to applicability of both HPLC as a separative technique and MS as a means of detecting analyte species.

Bioanalytical LC-MS method development for quantitative determination of drugs and their metabolites in biological fluids is crucial during drug development. The need for efficiently generated, regulatory compliant bioanalytical data is reliant on fit-for-purpose methods being developed and validated by experienced LC-MS scientists.

Our bioanalysis LC-MS teams are recognized for the ability to efficiently develop and validate routine and non-routine methods in a wide variety of matrices, and to rapidly employ these assays in a GLP-compliant and high throughput sample analysis environment.

What is preclinical testing?

In the process of preclinical testing of a compound or biological agent into a drug, the compound involved must go through the testing phase. First, we need to identify potential targets that can treat the disease. Then, a variety of compounds or preparations are screened out. Any compound that has shown potential as a drug for the treatment of this disease needs to be tested for toxicity before clinical testing to reduce the possibility of injury. preclinical testing What is the basis of preclinical testing? According to US Food and Drug Administration (FDA) regulations, a series of tests are required before a new drug is approved for use. In the first stage, basic research determines a hypothetical target for the treatment of a certain disease, and then screens small molecules or biological compounds to discover any substance with the potential to treat the disease. Then, a preclinical research phase followed, before which, as described above, the potential tox...

Inventory of the three major in vitro pharmacokinetic research methods

The metabolic properties of a compound are an essential factor in whether or not it can be used as a drug in the clinical setting, so pharmacokinetic studies of newly synthesized compounds are required in drug development. In vitro incubation with liver microsomes, recombinant CYP450 enzyme lines, and in vitro incubation with hepatocytes are some of the more common in vitro drug metabolism methods. 1. In vitro incubation method with liver microsomes The metabolic stability and metabolic phenotypes of candidate compounds in different species of liver microsomes are good predictors of the metabolic properties of compounds in vivo. They are practical tools for evaluating candidate compounds in the pre-development phase of drug development. Liver microsomes include rat liver microsomes, human liver microsomes, canine liver microsomes, monkey liver microsomes, and mouse liver microsomes. In in vitro incubation of the liver, microsomes are the "gold standard" for in vitro d...

Enzyme Activity Assay Service

Enzymatic assay Lance Assay Alphascreen Assay Z’-LYTE Assay Adapta Assay Kinase-Glo Assay ADP-Glo Assay Ligand Binding Assay ELISA Assay HTRF Assay Enzyme activity assays are laboratory methods for measuring enzymatic activity. They are vital for the study of enzyme kinetics and enzyme inhibition. Enzyme units : Amounts of enzymes can either be expressed as molar amounts, as with any other chemical, or measured in terms of activity, in enzyme units. Medicilon provides various enzyme activity assays for kinases , phosphatases, proteinases, deacetylase, peptidase, esterase, and other enzymes. Our line of well-characterized immunoassays and biochemical kits ensures accurate and reproducible results. Enzyme is a large category of bio-molecules that catalyze various biological processes including metabolic processes, cellular signaling and regulation, cell division and apoptosis. Enzymatic reactions convert substrate molecules into chemically modifi...
