3G-201 nucleic acid rapid test (visual LAMP method)

Goldlane Ltd acts on behalf of NKY Medical Holdings (a company listed on the Shenzhen stock exchange) and their subsidiary 3G Biotech. Our swab SARS-CoV-2 swab testing kit is a fully functioning rapid test kit  based on a visual isothermal amplification method without RNA extraction, has a simple operation and the test results can be analysed by the naked eyes in 30 minutes.    Loop-mediated isothermal amplification (LAMP) testing is a relatively new method of nucleic acid...

Reprocess used Negative Swabs Swabs

If a swab proves negative for Covid 19 use it again. Could be sterilised by irradiation or some other method. I don't know if this could be extended to all swabs obviously you need to get rid of any RNA but that wont be on the negative ones.

A simple, colour change based at-home diagnostic that is cheap and scalable

The idea relies on protein complementation technology, which is very well applied in life sciences research. Here we take advantage of camelid nanobodies that have recently been published ( https://www.biorxiv.org/content/10.1101/2020.03.26.010165v1 ) - these nanobodies bind to RBD domain of CoV S protein. Since S protein is a trimer, 2 nanobodies can bind each S trimer. So, by genetically engineering two constructs - one with nanobody fused to one half of the split enzyme, and other...

CoV-2 Antibody Test

My expertise is in medical devices. This test was proposed to me last month by my trusted partner in China. As I do not have the expertise to assess its credibility, I did not proceed. If, however, such a test, or components of the kit, could be of use I would happily request further information from the supplier.

Can we use the properties of SARS CoV2 to help choose simple to use swabs and swabbing procedures?

SARS CoV-2 and related coronaviruses have been shown to have a significant and persistent half life (up to 9 days) on a number of material surfaces particularly stainless steel but also a variety of plastics Including polypropylene,Teflon, PVC. (1,2) at ambient temperatures. Can this property be exploited to enable the use of very simple and widely available swabbing materials e.g. polypropylene rods or strips or pvc sheets or strips? For simple non quantitative tests which need to...

OM-505 and OR-100 devices - currently being tested in the USA

No I haven't. However, I have contacted the company DNA Genotek and this is one of the answers I received: "We do have more information regarding our kits and their use in COVID-19 testing including some relevant documentation, the account manager can connect with you to discuss these." "However we do not yet have data on samples collected with our devices. We do know that our stabilization solution can accommodate a very broad spectrum of microbiome activity spanning bacteria to...

Mail sterile kits with plastic pasteur pipettes and RNAlater or RNAstable eppendorfs to public

Safe idea for the general public without much expense or risk: 1. Mail sterile plastic pasteur pipettes to test subjects. 2. People extract a small tissue sample from nose, throat, etc. and transfer to small enclosed tube (eppendorf/similar) containing RNA later (Invitrogen). "RNA later Stabilization Solution is an aqueous, nontoxic tissue storage reagent that rapidly permeates tissues to stabilize and protect cellular RNA." Once in RNAlater (or RNAstable), RNA is stable for 24hrs at...
