Product Information

Assay Principle

Using the provided primer mix, biotinylated PCR products are generated from DNA extracts of ‘Food’ preparations containing meat or milk products. The labeled amplicons are hybridized to species specific capture probes immobilized on the LCD-Chip surface. Following a short wash routine, comprising high stringency, visualization of bound amplicons is mediated by an enzyme-substrate cascade. Each LCD-Chip contains eight identical micro arrays separated in small reaction chambers which can be addressed individually.

 

Target Region & Sensitivity

The primer mix is directed against highly conserved motifs within the mitochondrial 16S_rRNA genes of vertebrates. Specific capture probes immobilized as duplicates permit the simultaneous detection of 24 mammal and bird species most commonly used in ‘Food’ preparations. Due to the small amplicon sizes (120 – 130 bp) the assay is also well suited for the analysis of sample material which underwent intensive processing. Depending on the starting material, additions of less than 0.5 % material from any species can be detected within a background of 99.5% material from other species.
