应用

无色结晶紫用于鉴别干酪中产生组胺的乳酸菌[1]

生化/生理作用

无色结晶紫 (LCV) 是一种阳离子三芳甲烷染料。LCV 是龙胆紫(结晶紫)的还原形式,因此,它是无色的。对纤维素和蛋白质材料均有亲和力。LCV 和过氧化氢与血液中的血红蛋白发生反应,使血液印记变为紫色/紫罗兰色。因此,该染料广泛用于染色多孔和无孔材料上的血液残留物。[2][3]

Questions

1–2 of 2 Questions  
  1. Is 219215-5G the same powder that is used in the urinalysis dip sticks?

    1 answer
    1. Leucocrystal violet is the completely reduced form of crystal violet. The dye powder appears white to gray to lavender, and solutions are expected to be colorless. In addition to identifying lactobacilli in cheese, Leucocrystal Violet (LCV) is a cationic triarylmethane dye that has an affinity for both cellulosic and proteinaceous materials. It reacts with the hemoglobin in blood and turns the blood impression to a purple/violet color. Consequently, the dye is widely used to stain blood residue on both porous and non-porous materials. There is also mention of Leucocrystal Violet being used as an indicator on a urinalysis test strip, potentially to detect the presence of blood or protein. However, the quality level for Leucocrystal Violet is 200 on a scale of 100 to 600, and it is only advertised as suitable for Research Use Only. Urinalysis test strips sold for human use are classified as medical devices and are stated to be suitable for In Vitro Diagnostic Use. As such, product 219215 is not suitability tested to ensure the dye is suitble for use in the manufacture of urinalysis test strips.
