Application

Myoglobin from equine heart is suitable for use in:
  • spectral measurements in Beckman DU-50 or Gilford 2400 spectrophotometer
  • the secondary structure analysis of proteins in H2O solution using single-pass attenuated total reflection Fourier transform infrared (ATR-FT-IR) microscopy
  • the calibration of the mass scale at a concentration of 2 pmol/μL in Electrospray mass spectrometry
  • a study to investigate on-line single droplet deposition for MALDI mass spectrometry
  • a study to examine protein adsorption in fused-silica and polyacrylamide-coated capillaries

Biochem/physiol Actions

Myoglobin is a mobile carrier of oxygen that is developed in red muscle and heart cells. This happens as a response to elevated demand for oxygen during exercise, and transports oxygen from the sarcolemma to the mitochondria of vertebrate heart and red muscle cells.
