Beta-2 comprises C3 (complement protein 3). It is raised in the acute phase response. Depression of C3 occurs in autoimmune disorders as the complement system is activated and the C3 becomes bound to immune complexes and removed from serum. Fibrinogen, a beta-2 protein, is found in normal plasma but absent in normal serum.
LeDock is a molecular docking software, designed for protein-ligand interactions, that is compatible with Linux, macOS, and Windows. [2] [3] [4] The software can run as a standalone programme or from Jupyter Notebook. [5] It supports the Tripos Mol2 file format.
Byonic is a database search algorithm released in 2011 by Protein Metrics Inc. with original developments at PARC. [2] It searches MS/MS data from all types of instruments and internally employs the program Combyne, [3] which combines peptide identifications to produce protein scores and identification probabilities.

From 10,000 protein–protein interactions (PPIs) annotated for 3,000 proteins in 2003, HPRD has grown to over 36,500 unique PPIs annotated for 25,000 proteins including 6,360 isoforms by the end of 2007. [3] More than 50% of molecules annotated in HPRD have at least one PPI and 10% have more than 10 PPIs.
It was originally coined in reference to the use of limited proteolysis to investigate contact sites within a monoclonal antibody - protein antigen complex [1] and a year later to examine the protection from hydroxyl radical cleavage conferred by a protein bound to DNA within a DNA-protein complex. [2] In DNA footprinting the protein is ...
A reverse phase protein lysate microarray (RPMA) is a protein microarray designed as a dot-blot platform that allows measurement of protein expression levels in a large number of biological samples simultaneously in a quantitative manner when high-quality antibodies are available. [1]
The sodium dodecyl sulfate method requires a 5 minute pretreatment using 1% sodium dodecyl sulfate and can produce an increase in staining intensity by immunohistochemistry as well as immunofluorescence. [10] Heating en bloc takes tissue blocks fixated in paraformaldehyde, heats them in retrieval solutions, and then freezes them using dry ice.
Immunoprecipitation of intact protein complexes (i.e. antigen along with any proteins or ligands that are bound to it) is known as co-immunoprecipitation (Co-IP). Co-IP works by selecting an antibody that targets a known protein that is believed to be a member of a larger complex of proteins.
