Only recently the first examples for a site-selective conjugation between an ON therapeutic and a mAb was published: in 2015 Genentech exploited the SMCC linker to conjugate siRNA to several engineered mAb based on their proprietary Thiomab technology, which allows site-specific introduction of a cysteine into the antibody sequence[32].

A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
COVID-19 rapid antigen tests or RATs, also frequently called COVID-19 lateral flow tests or LFTs, are rapid antigen tests used to detect SARS-CoV-2 infection . They are quick to implement with minimal training, cost a fraction of other forms of COVID-19 testing , and give users a result within 5–30 minutes.
COVID-19 Antigen Rapid Test Kit; the timer is provided by the user. Mucus from nose or throat in a test liquid is placed onto a COVID-19 rapid antigen diagnostic test device. COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
Monoclonal antibody ibritumomab conjugated with tiuxetan Bioconjugation is a chemical strategy to form a stable covalent link between two molecules, at least one of which is a biomolecule . Methods to conjugate biomolecules are applied in various field, including medicine, diagnostics, biocatalysis and materials.
An antigen/adjuvant conjugate is injected into an animal of choice to initiate an amplified immune response. After a series of injections over a specific length of time, the animal is expected to have created antibodies against the conjugate. Blood is then extracted from the animal and then purified to obtain the antibody of interest.
The physical structure of an antibody allows it to bind to a specific antigen, such as bacterial or viral proteins, [6] to form a complex. [7] Because antibodies are highly specific in what they bind, tests can detect specific antibodies by replicating the antigen which that antibody binds to.
The first is producing the antibody that binds specifically to the antigen of interest and the second is fusing the tag to the antibody. Since it is impractical to fuse a tag to every conceivable antigen-specific antibody, most immunolabeling processes use an indirect method of detection.
