General description

The Sialic Acid Quantitation Kit provides a rapid and accurate determination of total N-acetylneuraminic acid (NANA; sialic acid). NANA is released from glycoconjugates using neuraminidase. The kit uses α(2→3,6,8,9) neuraminidase to cleave all NANA linkages, including α(2→8) and α(2→9) linkages, as well as branched NANA, for the most accurate determination of total sialic acid content.

Application

Contains all reagents to quantitate the amount of N-acetylneuraminic acid, either free, or in glycoproteins, cell surface glycoproteins, polysialic acids and capsular polysaccharides (consisting only of polysialic acid).

Quantity

Sufficient reagents are provided to perform 25 reactions, including control samples. Each reaction will measure 1-200 nmoles of NANA.

Posttranslational modifications are dynamic enzymatic-mediated processes, regulated in time and space, associated with cancer development. We aimed to evaluate the significance of posttranslational modifications in the pathogenesis of clear cell renal cell carcinoma. The authors developed a prospective, observational study

Tamm-Horsfall protein (THP) is thought to protect against calcium oxalate monohydrate (COM) stone formation by inhibiting COM aggregation. Several studies reported that stone formers produce THP with reduced levels of glycosylation, particularly sialic acid levels, which leads to reduced negative
