Hemoglobin equine has been used as a standard protein:
- to test solid-film sampling methodology in Fourier transform infrared spectroscopy (FT-IR) for protein secondary structure determination
- in capillary reversed-phase liquid chromatography-tandem mass spectrometry (LC/MS/MS) post enzymatic digestion
- for quantification of hemoglobin content from the planktonic crustacean, Daphnia magna
