Application
Myoglobin from equine heart is suitable for use in:
- spectral measurements in Beckman DU-50 or Gilford 2400 spectrophotometer[1]
- the secondary structure analysis of proteins in H2O solution using single-pass attenuated total reflection Fourier transform infrared (ATR-FT-IR) microscopy[2]
- the calibration of the mass scale at a concentration of 2 pmol/μL in Electrospray mass spectrometry[3]
- a study to investigate on-line single droplet deposition for MALDI mass spectrometry[4]
- a study to examine protein adsorption in fused-silica and polyacrylamide-coated capillaries[5]
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.[6]
