STUDY OBJECTIVE Limited information is available about the diagnostic performance of creatine kinase (CK)-MB and myoglobin levels during the early evaluation of chest pain patients using cardiac troponins as the criterion standard for diagnosing acute myocardial infarction. In this study, we compare the sensitivity and specificity of the baseline, 2-hour absolute, and 2-hour delta values of myo...

Myoglobin binds reversibly with oxygen and can facilitate oxygen diffusion across artificial membranes in vitro (Wittenberg, 1970). Myoglobin-enhanced oxygen consumption in heart is particularly important under conditions of hypoxia. This has been established directly with fish heart models (Bailey & Driedzic, 1986; Driedzic, Stewart & Scott, 1982) and indirectly by following discharge of high-...

We describe a simple, sensitive, and relatively inexpensive counterimmunoelectrophoretic technique for detection and estimation of myoglobin. The test can be completed within 90 min, compared with 12-48 h required by double immunodiffusion. With the counterimmunoelectrophoretic technique we could detect myoglobin in concentrations of 2-3 mg/liter, while the detection limit by double immunodiffu...

Double stranded DNA was cleaved oxidatively by incubation with oxygenated myoglobin, and Lys96Cys sperm whale myoglobin in its stable ferric form functioned as an artificial nuclease under air by formation of an oxygenated species, owing to electron transfer from the SH group of the introduced cysteine to the heme.

Whale skeletal muscle myoglobin (mol wt 17,800; molecular dimensions 25 x 34 x 42 A) was used as a probe molecule for the pore systems of muscle capillaries. Diaphragms of Wistar-Furth rats were fixed in situ at intervals up to 4 h after the intravenous injection of the tracer, and myoglobin was localized in the tissue by a peroxidase reaction. Gel filtration of plasma samples proved that myogl...
