制备方法与用途

苏木素是一种广泛应用于细胞学和组织化学中的染色剂,主要用于染色细胞核和染色质。它能够使这些结构呈现出深蓝色或紫色。以下是关于苏木素的一些重要信息:

苏木素的种类
  1. H&E染色:最常用的苏木素是用于与伊红混合进行HE染色(常规苏木素-伊红染色),主要用于一般组织切片的染色。
  2. 改良的苏木素液
    • Gill改良苏木素液
    • Mayer改良苏木素液
    • Ehrlich苏木素液

每种苏木素液都有其特点和适用范围,具体配方如下:

  • H&E染色:直接使用市售的HE染色试剂。

  • Gill改良苏木素液

    • 苏木精2g、无水乙醇250ml、硫酸铝17.6g、蒸馏水750ml、碘酸钠0.2g、冰乙酸20ml。
  • Mayer改良苏木素液

    • 苏木精2g、无水乙醇40ml、硫酸铝钾100g、蒸馏水600ml、碘酸钠0.4g。

    名称:
    Glucansucrases from lactic acid bacteria as biocatalysts for multi-ring catechol glucosylation
    摘要:
    Catechins are the major group of bioactive flavanols in green tea and cacao. 17 glucansucrase-active strains were identified from a set of 41 lactic acid bacteria, which were able to glucosylate (+)-catechin in a non-natural acceptor reaction. In total cell free extracts of 12Leuconostocand 5Weissellastrains were active on catechin and also 8 cell fractions exhibited catechin glucosylation activity. Six enzymes were selected for further evaluation and enriched up to 37 fold in yields of at least 40%. Glucansucrase ofL. citreumDSM 5577 was the most efficient biocatalyst for (+)-catechin transformation with conversions of >40% after 24 h. NMR analysis of the major reaction product confirmed the (+)-catechin-4 '-O-alpha-d-glucoside. OnlyL. kimchiB-65337 produced a second catechin monoglucoside. Four out of six glucansucrases glucosylated esculetin and all enzymes were active on haematoxylin. Glucansucrases ofL. citreumDSM 5577,L. kimchiB-65337 andW. beninensisDSM 22752 were the best suited biocatalysts with conversions of >30% for esculetin and >60% for haematoxylin.W. beninensisDSM 22752 glucansucrase produced 89% haematoxylin glucosides without process optimization.L. kimchiB-65337 andW. beninensisDSM 22752 synthesized >40% diglucosides with the bifunctional haematoxylin. NMR analysis of the purified esculetin products confirmed formation of the 6-O-alpha-d- and 7-O-alpha-d-glucosides. Also two haematoxylin monoglucosides were identified as the 9-O-alpha-d- and 3-O-alpha-d-glucosides.
