General description

BSA+TMCS combination, is one of the most commonly used silylating reagents. BSA is readily used for silylating a wide range of functional groups such as non-sterically hindered alcohols, amides, amines, amino acids, carboxylic acids, and enols. TMCS is a silylation catalyst always used with other silylation reagents to increase the reactivity in derivatization of alcohols, alkaloids, amines, biogenic amines, carboxylic acids, phenols, and steroids.

Application

Learn more in the Product Information
Suitable for the derivatization of α-ketoacids, amines, amino acids, cycloserine, histamine and metabolites, phenylethylamines, phosphatidylserines and tryptamines. BSA+TMCS may be used as a derivatizing reagent for the determination of steryl glycosides in biodiesel using gas chromatography–mass spectrometry.
Suitable for the derivatization of a-ketoacids, amines, amino acids, cycloserine, histamine and metabolites, phenylethylamines, phosphatidylserines and tryptamines.

Features and Benefits

  • BSA+TMCS has good solvent properties and can function as a silylation reagent without additional solvents.        
  • Alternatively, the mixture is very soluble in most commonly used silylation solvents.        
  • This combination is extremely sensitive to moisture and should be handled under dry conditions.

Other Notes

Reagent for trimethylsilyl diglyceride, trimethylsilyl (TMS) and trimethylsilyl oximes.
Powerful silylation mixture with wide applicability

Background and objective: Chronic relapsing inflammatory optic neuritis (CRION) is one of the more common phenotypes related to myelin oligodendrocyte glycoprotein antibodies (MOG-Abs). The absence of specific biomarkers makes distinguishing between CRION and relapsing inflammatory ON (RION) difficult. A recent...

Aberrant stem cell-like gene regulatory networks are a feature of leukaemogenesis. The ETS-related gene (ERG), an important regulator of normal haematopoiesis, is also highly expressed in T-ALL and acute myeloid leukaemia (AML). However, the transcriptional regulation of ERG in leukaemic...

There are currently no biosensors that are able to reliably detect the process of cancer metastasis. We describe the first label-free real-time ultra-high frequency acoustic wave biosensor prototype capable of detecting the breast and prostate cancer metastasis biomarker, parathyroid hormone-related...
