FAQ category: HLA Typing

NGSgo®, NGS-Turbo® and NGS-Pronto® products are available for the following HLA loci: HLA-A, B, C, DRB1, DRB3/4/5, DQA1, DQB1, DPA1, DPB1. Additionally, NGSgo is available for HLA-G (RUO only).

Yes, we have prototype reagents available for several genes. NGSgo-MoreMX includes HLA-DRA, -E, -F, -G, and -H, and HLA-related genes  MR1, MICA, and MICB. Additionally, singleplex prototypes are available for HLA-E and HLA-F. Amplification strategies are also available for HLA-G, KIR and MICA/MICB (RUO). In addition, there is a prototype amplification strategy for 11 rare blood group systems.

HLA sequencing using short reads:

• NGSgo-AmpX v2/3 for single locus amplification of HLA-A/B/C/DRB1/DRB3/ DRB4/DRB5/DQA1/DQB1/DPA1/DPB1 and HLA-G (NGSgo-AmpX v2).
• NGSgo-MX6-1 for multiplex amplification of HLA-A/B/C/DRB1/DQB1/DPB1
• NGSgo-MX11-3 for multiplex amplification of HLA-A/B/C/DRB1/DRB3/ DRB4/DRB5/DQA1/DQB1/DPA1/DPB1
• NGSgo Library Full Kit for library preparation compatible with above mentioned amplification strategies

HLA sequencing using long reads:

• NGS-Turbo: NGS-TurboAmp & NGS-TurboPrep for multiplex amplification & library preparation of HLA-A/B/C/DRB1/DRB3/DRB4/DRB5/DQA1/DQB1/DPA1/DPB1
  • HLA typing under 3h
• NGS-Pronto: NGSgo-ProntoAmp & NGS-ProntoPrep for multiplex amplification amplification & library preparation of HLA-A/B/C/DRB1/DRB3/ DRB4/DRB5/DQA1/DQB1/DPA1/DPB1

Software for analysis of sequencing data:

• NGSengine for NGSgo-AmpX v2/3, NGSgo-MX6-1 and NGSgo-MX11-3
• NGSengine-Turbo for NGS-Turbo and NGS-Pronto

Both NGSgo-AmpX kits are designed as single locus amplification strategy featuring exactly the same coverage per locus. The difference between the two kits is the polymerase enzyme. NGSgo-AmpX v2 contains the GenDx-LongMix enzyme, and NGSgo-AmpX v3 uses GenDx-LongZyme. Both enzymes perform well, but GenDx-LongZyme (v3) shows a slightly more robust amplification results with les lot-to-lot variation.
