Aalto Bio Reagents Recombinant SARS-CoV-2 Spike Proteins
Dublin-based Aalto Bio Reagents has released a range of recombinant SARS-CoV-2 spike (S) proteins for diagnostic test manufacturers, vaccine developers, and researchers globally. The S protein is the main antigenic component that is responsible for inducing host immune responses and neutralizing antibodies, making it the principal focus of therapeutic and vaccine design for COVID-19. When used solely or in combination with Aalto's new insect-derived nucleocapsid protein (N), the company's S1-S2 chimeric glycoprotein has demonstrated excellent reactivity in ELISA for the detection of IgA, IgG and IgM antibodies against SARS-CoV-2, the company said.
Thermo Fisher Scientific Invitrogen RiboMinus Bacteria 2.0 Transcriptome Isolation Kit
Thermo Fisher Scientific has released the Invitrogen RiboMinus Bacteria 2.0 Transcriptome Isolation Kit for the probe-based depletion of ribosomal RNA from bacteria. The kit, which can be automated on Thermo Fisher KingFisher instruments, uses a novel magnetic bead-based purification technology to selectively deplete rRNA transcripts from total RNA. It now includes 5S targets and more than 100 probe designs to yield improved rRNA depletion and can be utilized with RNA from a wide variety of species.
Oxford Immunotec T-Spot Discovery SARS-CoV-2 RUO Kit
Oxford Immunotec Global has launched the T-Spot Discovery SARS-CoV-2 test kit for research use only. The kit builds on its experience with tuberculosis diagnosis and the assessment of the immune response to cytomegalovirus infections in transplant patients. Using the company's established T-Spot technology, the kit interrogates the immune system's T-cell response and will enable research into the measurement of the strength of that response to SARS-CoV-2, Oxford Immunotec said.
