Microreader™ 23sp Direct ID System is a forensic grade product with 5-dye fluorescent technology and a co-amplification method to detect 23 loci including 21 non-CODIS loci, 1 CODIS loci, and Amelogenin. It is specifically designed for supplementary STR testing for paternity and kinship testing in complex relationship and to obtain a huge amount of information.

The Kit is subjected to rigorous quality control testing to offer consistent performance. We develop and manufacture our products in accordance with ISO 9001 and ISO 18385 quality system requirements.

As an addition to regular paternity DNA test, Microreader™ 23sp Direct ID System greatly improves probability of discrimination power (DP) and excluding probability of paternity (PE) due to the choice of non-linked loci. The cumulative non-father exclusion rate CPE>0.999 999 999.

It can be used with Microreader™ 21 Direct ID System to detect up to 39 autosomal STR loci. Enable the comprehensive detection of supplementary STR loci.

Without the need for sample extraction, purification and quantification, the entire process from direct amplification of the samples to the PCR product can be completed in 90 minutes, which improves the work efficiency and reduced testing costs, which are very suitable for the processing of large batches of samples.

As an autosomal complementary paternity test Kit, it can be used together with the mainstream kits in the market, such as ABI: Globalfiler, Promega: VersaPlex 27PY, etc, from the angle of phylogenetic identification, increase the accuracy of screening.
