Alendronic acid or Alendronate Sodium is a bisphosphonate drug that inhibits osteoclast-mediated bone resorption. Biphosphates work by binding to the bone and preventing calcium from being removed by osteoclasts. This drug is used to prevent and treat osteoporosis as well as several other bone diseases. Alendronate Sodium is sold as tablets or solutions, alone or in combination with Vitamin D.
Since Alendronic acid has no chromophore, post-column derivatization is employed to produce
Pickering Laboratories specializes in the manufacturing of cation-exchange columns and eluants for amino acid analysis. Post-column derivatization with Ninhydrin offers unmatched selectivity and reproducibility of the analysis for most challenging matrixes.
Pinnacle PCX post-column derivatization system allows analysts to combine eluant gradient capabilities of modern HPLC instruments with column temperature gradients. We introduce new accelerated Amino Acids Analy¬sis method for
Phenylketonuria (PKU) and Maple syrup urine disease (MSUD), branched-chain ketoaciduria are genetically transmitted metabolic diseases. PKU results in elevated Phenylalanine levels due to deficient activity of the enzyme Phenylalanine hydroxylase. In the MSUD state, elevated levels of leucine (Leu), isoleucine (Ile), valine (Val), and alloiso-leucine can be detected in blood. The increased concentration of the branched-chain amino acids is caused by an inherited deficient activity of the enzy
Aminoglycoside antibiotics are among those commonly used in animal feeds to manage intestinal microorganisms. The beneficial effects include improved growth and generally healthier animal populations. Use of antibiotics creates a demand for analytical procedures to verify concentrations in pre-mixes and feeds and in some instances for residue analysis in animal products. This note describes a simple, robust analytical method for the family of Aminoglycoside antibiotics in feeds and animal pro
