  • PowerSeq 46GY
  • ForenSeq Signature Prep/Plus and MainstAY (Does not cover the whole ISFG minimum range.)
  • Precision ID GlobalFiler NGS STR Panel v2
  • IDSeek OmniSTR Global (Does not cover the whole ISFG minimum range.)

Kit range does not cover the whole ISFG minimum range of this locus (chr8:124,894,859-124,894,922), according to the kit ranges in the FSSG. Bases of the minimum range outside a kit's range are not sequenced by that kit; bases filled in from the reference should be identified as such.

ForenSeq MainstAY/Signature Prep range shown is exclusive of primer, inferred bases may be included in UAS output.
