The MMA is a very labor-intensive, manual laboratory testing method. The following steps are performed in this assay: [13] Anticoagulated blood is collected from normal, healthy individuals. Acid citrate dextrose is preferred. [6] Peripheral blood mononuclear cells (PBMC) are harvested from the blood sample using a Ficoll-Paque® density gradient.
Each monomer of human α 2-macroglobulin is composed of several functional domains, including macroglobulin domains, a thiol ester-containing domain and a receptor-binding domain. [9] Overall, α 2 -macroglobulin is the largest major nonimmunoglobulin protein in human plasma.
Levels of fibrin monomers can be measured using blood tests and can serve as a marker of in vivo fibrinogenesis and coagulation activation. [ 1 ] [ 2 ] [ 3 ] They may be useful in the evaluation of hypercoagulability , [ 1 ] as reflected in research studies done using fibrin monomers.
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
A protein structure database is a database that is modeled around the various experimentally determined protein structures. The aim of most protein structure databases is to organize and annotate the protein structures, providing the biological community access to the experimental data in a useful way.
Immunoglobulin M (IgM) is the largest of several isotypes of antibodies (also known as immunoglobulin) that are produced by vertebrates.IgM is the first antibody to appear in the response to initial exposure to an antigen; [1] [2] causing it to also be called an acute phase antibody.
Illustration showing influenza virus attaching to cell membrane via the surface protein hemagglutinin. Hemagglutinins (alternatively spelt haemagglutinin, from the Greek haima, 'blood' + Latin gluten, 'glue') are homotrimeric glycoproteins present on the protein capsids of viruses in the Paramyxoviridae and Orthomyxoviridae families.
The BChl a molecules are depicted in green, the central magnesium atom in red and the protein in grey ("cartoons" representation). Each monomer contains bacteriochlorophylls. The Fenna–Matthews–Olson (FMO) complex is a water-soluble complex and was the first pigment-protein complex (PPC) to be structure analyzed by x-ray spectroscopy. [2]
