SEMANTIC ANALYSIS

ⓘ The owner has associated the following topics to the website.

ⓘ The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by ptglab.com.

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

Topics

Proteintech Confidence: 86%

Proteintech Group is a multinational biotechnology company with offices based in Chicago, Europe (Manchester, UK) and China (Wuhan). Founded as a start-up company in Chicago in 2002, it supplies polyclonal and monoclonal antibodies to the medical and life science research community.

Antibody Confidence: 79%

An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as bacteria and viruses. The antibody recognizes a unique molecule of the harmful agent, called an antigen, via the Fab's variable region. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival). Depending on the antigen, the binding may impede the biological process causing the disease or may activate macrophages to destroy the foreign substance. The ability of an antibody to communicate with the other components of the immune system is mediated via its Fc region (located at the base of the "Y"), which contains a conserved glycosylation site involved in these interactions. The production of antibodies is the main function of the humoral immune system.

ELISA Confidence: 73%

The enzyme-linked immunosorbent assay (ELISA) is a test that uses antibodies and color change to identify a substance.

Medical research Confidence: 67%

Quality control Confidence: 66%
