  2. Isozyme - Wikipedia

    en.wikipedia.org/wiki/Isozyme

    In particular, amino acid substitutions that change the electric charge of the enzyme are simple to identify by gel electrophoresis, and this forms the basis for the use of isozymes as molecular markers. To identify isozymes, a crude protein extract is made by grinding animal or plant tissue with an extraction buffer, and the components of ...

  3. Cardiac marker - Wikipedia

    en.wikipedia.org/wiki/Cardiac_marker

    Cardiac markers are biomarkers measured to evaluate heart function. They can be useful in the early prediction or diagnosis of disease. [ 1 ] Although they are often discussed in the context of myocardial infarction , other conditions can lead to an elevation in cardiac marker level.

  4. CPK-MB test - Wikipedia

    en.wikipedia.org/wiki/CPK-MB_test

    The CPK-MB test (creatine phosphokinase-MB), also known as CK-MB test, is a cardiac marker [3] used to assist diagnoses of an acute myocardial infarction, myocardial ischemia, or myocarditis. It measures the blood level of CK-MB (creatine kinase myocardial band), the bound combination of two variants (isoenzymes CKM and CKB ) of the enzyme ...

  5. Creatine kinase - Wikipedia

    en.wikipedia.org/wiki/Creatine_kinase

    Thus creatine kinase is an important enzyme in such tissues. [3] Clinically, creatine kinase is assayed in blood tests as a marker of damage of CK-rich tissue such as in myocardial infarction (heart attack), rhabdomyolysis (severe muscle breakdown), muscular dystrophy, autoimmune myositides, and acute kidney injury. [4]

  6. Biomarker (medicine) - Wikipedia

    en.wikipedia.org/wiki/Biomarker_(medicine)

    In medicine, a biomarker is a measurable indicator of the severity or presence of some disease state. It may be defined as a "cellular, biochemical or molecular alteration in cells, tissues or fluids that can be measured and evaluated to indicate normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention."

  7. ELISA - Wikipedia

    en.wikipedia.org/wiki/ELISA

    The following table lists the enzymatic markers commonly used in ELISA assays, which allow the results of the assay to be measured upon completion. OPD ( o -phenylenediamine dihydrochloride) turns amber to detect HRP ( horseradish peroxidase ), which is often used to as a conjugated protein .

  8. CD38 - Wikipedia

    en.wikipedia.org/wiki/CD38

    About the same time, CD38 was discovered to be not simply a marker of cell types, but an activator of B cells and T cells. [10] In 1992 the enzymatic activity of CD38 was discovered, having the capacity to synthesize the calcium-releasing second messengers cyclic ADP-ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate (NAADP). [10]

  9. Biomarker - Wikipedia

    en.wikipedia.org/wiki/Biomarker

    In biomedical contexts, a biomarker, or biological marker, is a measurable indicator of some biological state or condition. Biomarkers are often measured and evaluated using blood, urine, or soft tissues [ 1 ] to examine normal biological processes , pathogenic processes, or pharmacologic responses to a therapeutic intervention .
