Propargyl-PEG12-methylamine is a propargyl linker that is commonly used as a Click Chemistry reagent for copper-catalyzed reactions with azides. The methylamine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The PEG spacer helps improve the water solubility of the molecule in aqueous media. Reagent grade, for research use only.

Method recognition:
Improved method
The Acetic Acid GK format test kit is for use with auto-analysers and is suitable for the specific measurement and analysis of acetic acid (acetate) especially in wines, fruit juices, beverages and food products.
As part of Megazyme’s overall commitment to providing the highest quality products, we have developed this acetic acid kit that provides a specific and rapid assay for use with auto-analysers. The kit assay is based on the conversion of NAD+ to NADH and therefore provides a positive reaction (increase in absorbance) which offers a more robust assay.
The reagents, as supplied, are stable for a minimum of 2 years and the prepared reagents are stable for a minimum of 1 week (on-board stability). In addition, the prepared reagents can be stored frozen for longer term stability (see K-ACETGK Booklet for more details).

SRY (Sex Determining Region Y)-Box 10 (SOX-10), also known as transcription factor SOX-10, is a nuclear transcription factor that acts in regulation of embryonic development and in the specification and differentiation of cells of melanocytic lineage. SOX-10 is diffusely expressed in neurofibromas and schwannomas, and mutations in the SOX-10 gene are linked to Waardenburg-Shah and Waardenburg-Hirschsprung disease. Anti-SOX-10 has been shown to be sensitive for conventional, spindled, and desmoplastic melanoma, and has been used to detect metastatic melanoma and nodal capsular nevus in sentinel lymph nodes.
