Application

Myoglobin from equine skeletal muscle was used in a study to test experimental protein mixture for validating tandem mass spectral analysis.[1]

Biochem/physiol Actions

Myoglobin from horse skeletal muscle is a single chain heme protein containing 153 amino acid residues.[2] It possesses no disulfide bridges or free -SH groups. Myoglobin contains 8 variously sized right-handed helical regions, joined by non-ordered or random coil regions.[3]
Myoglobin is critical to skeletal muscle O2 supply at near-maximum oxygen demand, and prevents anoxia by maintaining PO2 above levels needed to support mitochondrial function.

Questions

1–3 of 3 Questions  
  1. Can you advise what the % level of hemoglobin (if any will be present in this product)? Or can this be treated as Hb contaminant free.

    1 answer
    1. While this product is not specifically tested for hemoglobin, it is purified by Sephadex gel filtration. Given the molecular weight differences between these two compounds, the presence of hemoglobin is highly unlikely.

  2. Can you share the amino acid sequence of this protein? M0630

    1 answer
    1. This product is a native protein that has not been modified during the extraction and purification process. The sequence of this product is published information. Please refer to the information in the UniProt database: https://www.uniprot.org/uniprotkb/P68082/entry

      Helpful?

  3. Is this myoglobin detectable using immunoenzymatic assay?

    1 answer
    1. Unfortunately, none of the equine myoglobin products have been tested for suitability in ELISA. Performance of these products in immunoenzymatic assays cannot be validated.
