Hemin (haemin; ferric chloride heme) is an iron-containing porphyrin with chlorine that can be formed from a heme group, such as heme B found in the hemoglobin of human blood. Meer weergeven Hemin is protoporphyrin IX containing a ferric iron (Fe ) ion with a coordinating chloride ligand. Chemically, hemin differs from the related heme-compound hematin chiefly in that the coordinating … Meer weergeven A lyophilised form of hemin is used as a pharmacological agent in certain cases for the treatment of porphyria attacks, particularly in Meer weergeven Hemin can be produced from hemoglobin by the so-called Teichmann test, when hemoglobin is heated with glacial acetic acid (saturated with saline). This can be used to detect blood traces.

WebNicotinamide adenine dinucleotide (NAD) has always served as an excellent V factor to support H. influenzae growth (Artman et al. 1973; Kuklińska and Kilian 1984). Hemin has consistently been used as an X factor supplement, as it is an essential source of iron and porphyrin for several WebThis inconsistent morphology and often variable staining (especially with saphronin in the Gram stain) may lead to diagnostic confusion in the clinical microbiology laboratory. Most Haemophilus spp. require two supplements—factors X (haemin) and V (nicotinamide adenine dinucleotide, NAD)—for aerobic growth on artificial culture media. WebA Haemophilus Quad plate was inoculated with a clinical specimen. There was no growth in the quadrant with hemin and no growth in the quadrant with NAD. There were small, grey colonies in the quadrant with both hemin and NAD. The horse blood quadrant showed growth with no hemolysis. thermostatische radiatorknop vervangen
