A sample stacking-capillary electrophoresis method for simultaneous determination of nitrate and thiocyanate ions of ultra-heat-treated milk samples

tailieu.vn

Despite several applications of capillary electrophoresis (CE) in the determination of nitrate and thiocyanate in meat and vegetable samples, 18 no studies have been conducted on milk samples with this method.. reported an MEKC method, which involves prepurification for two ions in biological fluids. To the best of our knowledge, a simple capillary electrophoresis method for determination of nitrate and thiocyanate in milk samples is not available in the literature.

Simultaneous determination of dexpanthenol, lidocaine hydrochloride, and mepyramine maleate in combined pharmaceutical gel by capillary electrophoresis

tailieu.vn

Simultaneous determination of dexpanthenol, lidocaine hydrochloride, and mepyramine maleate in combined pharmaceutical gel by capillary electrophoresis. Abstract: A new capillary electrophoresis method was developed for the simultaneous determination of dexpanthenol (DEX), lidocaine (LID), and mepyramine (MEP) in pharmaceutical preparations. The best results were obtained using 20 mM (pH 3.0) phosphate buffer as the background electrolyte.

Although many protocols exist, the most commonly used strategy currently uses the capillary electrophoresis-based Sanger method in which dideoxynucleotides are used to randomly terminate DNA polymerization at each of the four bases (A,G,T,C).

A procedure to detect 6 basic STSs and 11 extended STSs in the AZF region using multiplex PCR

tailieu.vn

The present techniques applied to simultaneously find multiple STSs are capillary electrophoresis and multiplex PCR. While capillary electrophoresis requires a sequencing system, multiplex PCR is simpler and does not require a lot of expensive equipment. Therefore, this study deployed a new design to primer sequences and simultaneously amplify multiple STSs in a multiplex PCR reaction. This study intends to integrate 17 STSs into three multiplex PCR reactions.
