The K-LOLAC test kit offers a rapid, novel, sequential measurement of free-glucose and lactose in conventional, low-lactose and lactose-free dairy products. This sequential assay format reduces the manual input required by an analyst when compared to traditional lactose assay formats and therefore improves both accuracy and efficiency. When used in combination with the Megazyme Creep Calculator provided, the β-galactosidase employed in this kit allows for the selective measurement of lactose in the presence of galacto-oligosaccharides (GOS) which are commonly found in lactose-free dairy products. This constitutes a significant improvement over existing commercially available lactose assay kits which typically overestimate lactose content in lactose-free samples due to the unselective hydrolysis of GOS by β-galactosidase. Lastly, the sensitivity of the K-LOLAC assay kit has been doubled through the use of a cascade biochemical pathway, helping to significantly reduce the LOD and LOQ for the assay.
We offer more monosaccharide and oligosaccharide assay kit products.

Validation of Methods
Advantages
As this is a 2 gene kit, we recommend purchase of 2 of the accompanying RT-qPCR master mix reagent: oasig Lyophilised OneStep RT-qPCR Master Mix 150 reactions.
Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.
The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit. Details of the target and priming specificity are included in the individual handbooks above.

This kit provides a convenient and rapid method to purify total RNA from small amounts of stool samples. All types of stool samples can be processed with this kit, including animal fecal samples, manure and samples collected using Norgen’s Stool Nucleic Acid Collection and Transport Devices Dx (Cat. Dx45660). The kit removes all traces of humic acids using rapid and simple spin column procedures. Bead tubes are also provided for effective homogenization of stool. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA and small interfering RNA. Both host and microbial RNA is recovered. The protocol does not rely on the use of phenol or chloroform, thereby providing a user friendly procedure and allowing high-throughput analysis. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR and reverse transcription PCR for gene expression analysis. The procedure can be completed in approximately 30 minutes.
