Methods based on this principle have been accepted by MEBAK
Ammonia Assay Kit, for the rapid measurement and analysis of ammonia in all samples, including grape juice and wine (and other foods/beverages).
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
The genesig® Dengue, Zika and Chikungunya Virus Multiplex kit is designed for the detection and differentiation of Dengue virus, Zika virus (ZIKV) and Chikungunya virus (CHIKV) only. Individual tests have been designed in the conserved regions of each virus such that all isolates and subtypes will be detected simultaneously in the same test. The Dengue component of the test will detect subtypes 1, 2, 3 and 4 but will not differentiate between them. A positive Dengue test results indicates that the sample has either one of these four subtypes.
The primers and probe sequences in this kit have 100% homology with a broad range of clinically relevant reference sequences based on a comprehensive bioinformatics analysis. They therefore have a very broad quantification profile.

Disulfide Biotin alkyne is an azide-activated cleavable biotin probe that allows for efficient recovery of avidin-bound protein complexes in affinity-based assays. This reagent contains a biotin moiety linked to an alkyne group through a spacer arm containing a cleavable disulfide linker. Under reducing conditions (50 mM dithiothreitol, 10 mM 2-mercaptoethanol or 1% sodium borohydride), the disulfide bonds are cleaved, releasing the biotin tag and any avidin conjugate bound to it.
