Going back to the flyer, (the IFU is not available):
https://genesig.com/assets/files/mm142_issue_2_snpsig_sars_cov_2_e484k_easy.pdf
"• Streamlined workflow for easy use with ready prepared Mastermix magazines that are individually packed and internal controls for run validity."
- So not lyophilised.
"• Each kit is suitable for running 3 separate runs on the genesig® q32 instrument."
- This is the only instrument mentioned, so not open platform.

From 17.05.21 RNS:
"· SNPsig® SARS-CoV-2 (E484K) Easy is a research-use-only, streamlined workflow solution for the detection of SARS-CoV-2 variants carrying the E484K escape mutation for use with the Company's q32 rapid-PCR instrument. This assay comes with pre-filled cassettes and includes only one pipetting step to decrease operator complexity and improve cycle times."
- This is the only instrument mentioned, so not open platform.

From 17.05.21 RNS:
"· Detecting known VoC Framework, announced by NHS England on 14 May 2021, includes the Company's SNPsig® SARS-CoV-2 PCR genotyping portfolio as one of the four companies selected by NHS England. This national framework is for testing of all positive SARS-CoV-2 samples from NHS (pillar 1) and high throughput Lighthouse (pillar 2) laboratories in England."
so the logical conclusion is that the E484K mutation is seen in multiple current VOC and is called an escape mutation because it helps the virus slip past the body’s immune defences to evade host antibodies and may, as a result, diminish the efficacy of immunisation.
This mutation can only be detected on q32 instruments in pillar 1 labs, as we can expect to find no q32 instruments in pillar 2 (lighthouse) labs.

From the presentation @ 10:0 mins - Ajan Reginald:
"Our industry leading Bioinformatics platform has been applied to our Covid, Covid plus and Post Covid portfolio.
This is an automated platform that allows us to analyse over 2 million genetic sequences / week to identify
mutations, but also to utilise machine learning to identify the best diagnostic targets, and the best assay design.
This is a key source of competitive advantage, and unprecedented amongst our IVD peers.
This allows us to generate novel, innovative assays that underpin our broad patent portfolio."
I believe Ajan is talking about the in silico (computer simulation) analysis of sequenced mutations mentioned in the 21.12.2020 RNS.
More competitive advantage :o)
