XFiling™ Kit v2.2 Allelic Ladder

The XFiling™ v2.2 Allelic Ladder is a dedicated allelic reference for analyzing results from the XFiling™ v2.2 human identification kit. This product contains a selected set of alleles for the kit’s STR markers (an X-chromosome marker panel), and by providing the reference positions of the alleles, it helps ensure accurate allele identification and designation (Allele Calling) in analysis software.

This Allelic Ladder includes selected alleles for the markers DXS1187, D21S11, DXS10101, DXS10146, DXS7132, DXS7423, DXS10148, DXS10135, HPRT, DXS10074, DXS6803, DXS10134, AMXY, DXS10103, DXS10079, DXS981, and DXS8378.

For analysis, the Allelic Ladder is prepared just like a PCR product and is electrophoresed alongside the samples on a Genetic Analyzer. After electrophoresis, the Ladder file is imported together with the sample files into an analysis software such as GeneMapper™ ID/ID-X. Using the Allelic Ladder that matches the corresponding kit and product version is essential for accurate Allele Calling and correct result interpretation.

To view the complete list of alleles, the allelic range of each marker, and the reference electropherogram, please refer to the User Manual of the XFiling™ v2.2 kit in the product documentation section of the Kawsar Biotech website.
