[43] Determination of aberrant hemoglobin derivatives in human blood

Sulfide-hemoglobin interactions in the sulfide-tolerant salt marsh resident, the California killifish Fundulus parvipinnis

“…denatured ferric hemichrome (with bands at 535 and 565 nm). or denatured ferrous hemochrome (with bands at 527 and 557 nm) based on the literature [summarized by Salvati and Tentori (1981); Tentori and Salvati (198l)J. SHb spectra, ferric and ferrous, with and without vanous ligands.…”

NMR Relaxometric Investigation on Human Methemoglobin and Fluoromethemoglobin. An Improved Quantitative in Vitro Assay of Human Methemoglobin

“…[6], derived from Eq. [5] HbO2 % For comparative purposes, the calibration curve previously determined for met-Hb (in the absence of fluoride) (7) is also reported in Fig.…”

“…Indeed, "the available techniques are suitable for clinical diagnosis of hereditary methemoglobinemia or severe intoxication, but give scant precision in the normal range and, at any rate, below 10% values" (5,6).…”

Peer Reviewed: False Cyanide Detection

“…Hb 3+ is produced from oxyhemoglobin (Hb 2+ -O 2 ) by an autoxidation mechanism and again converted to deoxyhemoglobin (Hb 2+ ) by the reduced form of nicotinamide-adenide dinucleotide phosphate (NADPH) met-hemoglobin reductase system in erythrocytes. The Hb 3+ content in normal blood is 0.5-1.0% (24). Therefore, at least 1 µg/mL of cyanide is assumed trapped in blood all the time.…”
