## Context
The papers-lamp subcategory contains a curated selection of published papers on RT-LAMP (reverse transcription loop-mediated isothermal amplification) tests for SARS-CoV-2 detection. The collection includes work from academic groups and commercial entities whose efforts were particularly relevant to FloodLAMP's development and operations during the pandemic. This is not a comprehensive literature review — it is a somewhat haphazard selection of papers that intersected directly with FloodLAMP's work or that represent notable milestones in LAMP-based COVID-19 testing.


## Commentary Points
The foundational paper in the collection is Rabe and Cepko (2020, PNAS), which describes the assay that FloodLAMP adopted as the basis for its testing protocol. The Rabe-Cepko test offered both a purified version — using a low-cost "glass milk" silica purification method — and a direct (extraction-free) version. FloodLAMP initially used the purified version before transitioning to the direct protocol for its subsequent clinical validation and FDA submissions as well as all of its surveillance pilot testing programs. A companion clinical validation paper (Anahtar, Rabe, et al., 2021) further established the assay's performance. In this archive's lamp-tech subcategory there is additional technical background on this assay, including an interview with Brian Rabe about the test's development.

Several papers represent groups that were central to the open-source LAMP testing community. The Kellner et al. paper from the Vienna BioCenter describes an open RT-LAMP assay developed by a group that was a prominent contributor to the gLAMP (Global LAMP) consortium. The Vienna group established rtlamp.org, a resource hosting open protocols, background information, how-to guides, and eventually distributing test kits. The various/glamp subcategory of this archive provides more information. Dave O'Connor's group at the University of Wisconsin contributed multiple papers on direct RT-LAMP evaluation and optimization. O'Connor also shared surveillance program documentation that is cross-referenced elsewhere in the archive. Nathan Tanner and colleagues at New England Biolabs (NEB) published papers on both foundational LAMP methodology and practical applications — including an extraction-free saliva RT-LAMP workflow for workplace surveillance conducted in partnership with Mirimus. Tanner was a key contributor to the GLAMP community, and NEB's colorimetric LAMP master mix reagent was a critical supply for FloodLAMP and many other LAMP-based testing efforts.

On the commercial side, Color Genomics obtained FDA Emergency Use Authorization for a purified, fluorometric LAMP assay read on a PCR thermal cycler. Color's test was widely deployed in screening programs across the San Francisco Bay Area, including at Stanford University and numerous companies. Its authorization and scale of deployment served as an important validation that LAMP-based molecular testing could function as a practical alternative to RT-PCR in large screening programs. The collection also includes a paper from Domus, which developed a lyophilized colorimetric RT-LAMP kit; Domus was a recipient of late-stage RADx (Rapid Acceleration of Diagnostics) funding from NIH.

Additional papers in the collection represent other notable academic efforts in LAMP-based SARS-CoV-2 detection, including work from Stanford (Prakash, using the Rabe-Cepko protocol with a low-cost centrifuge), UPenn (Sherrill-Mix on molecular beacons; Song on closed-tube detection), University of Chicago (Wang, saliva-based assays), and groups working in sub-Saharan Africa (Marcello et al., multicenter evaluation). An AI-generated literature review included in the subcategory extends coverage to 20 additional papers prioritized for large-scale testing and pandemic preparedness. The subcategory also includes a citations file with full bibliographic references and links for all papers in the collection.
