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.
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. CHIMERYS Proprietary
A mass spectrometer used for high throughput protein analysis. Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins.Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.
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.
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.
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]
A positive test shows a bluish-white streak of precipitated proteins. The degree of turbidity depends on the amount of protein in the CSF. It can vary from faint turbidity (mild to moderate elevation in CSF proteins) to dense milky precipitate (high protein content in CSF).
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.
