    • 14Life Technologies™ | •  Amelogenin  Y  null  alleles  can  occur   •  Addi9onal  Y  tes9ng  may  be  required  to  confirm  sample  gender     •  Addi9onal  gender  iden9fica9on  markers  are  on  the  long  arm  of  the  Y  chromosome   to  minimize  the  risk  of  a  double  dele9on   •  DYS391  is  a  stable  locus  with  a  rela9vely  narrow  allele  range     •  The  Y-­‐indel  is  very  short  therefore  more  likely  to  perform  even  if  DYS391  drops  out   in  degraded  samples   p q Amelogenin   Y-­‐indel/DYS391   Why Include Additional Y Markers?
    • 15Life Technologies™ | • Gender identification redundancy helps remove the need for laboratories to maintain a second gender confirmation test protocol • In addition, the Y-indel position (<90 bp) in the GlobalFiler™ Kit helps improve data recovery in degraded samples ♂ ♀ Improved Accuracy of Gender Determination

Mark the Master Mix tube with a + to indicate MM Additive was added. Discard Additive tube. 4)  Master Mix is ready for use and to be stored at 4ºC (Standard Protocol).

    • 44Life Technologies™ | GlobalFiler™ Kit: Test Site Feedback “The baseline is perfect, no artifact was observed in negative controls. Sample profiles have showed good quality data with a good balance PHR.”   “The fact that we are able to use up to 15µL of DNA per PCR reaction improves the sensitivity … very interesting for the amplification of poor DNA samples (<50pg/ µL).”   “Having 50% of the PCR products with a size less than or equal to 220bp allows better amplification of degraded DNA. In addition, with a volume of 15µL of DNA per PCR reaction, we are in the best conditions for amplification of degraded DNA with an amount of DNA lower than100pg/µL.”   “Seems to withstand well to inhibitors…”  
    • 45Life Technologies™ | GlobalFiler™ Kit: Test Site Feedback “Thanks to the integration of DYS391 and the Y-indel we can no longer have any doubt concerning the analysis of the Y chromosome in the case of amelogenin mutation.”   “Using a 6th dye allows to separate the markers analyzed and thus avoid allele overlap between neighboring markers.”   “The use of this kit should reduce the sample rate that has to be re-amplified whether with the same PCR kit or with another kit, while improving performance…”   “PCR  dura9on  (1:20  vs.   2:30  with  Iden9filer®  Plus)   is  also  an  advantage   especially  in  the  context  of   custody…”
