一般描述
乳糖特性: 由哺乳动物的乳中分出的一种双糖。牛乳中约含4%-5%,人乳中约含6.7%。经酸性水解得等分子的D-葡萄糖和D-半乳糖。是还原糖,能还原费林溶液。在常温水溶液中结晶得α-乳糖,在93℃以上结晶得β-乳糖。α-乳糖即普通的乳糖。有微弱的甜味,快速加热,其水溶液有变旋现象,[a]20D-92.6°→+83.5°(10分钟)→+69°(50分钟)→+52.3°(22小时)。β-乳糖比α-乳糖稍甜。其水溶液也有变旋现象。[α]25D+34°(3分钟)→+39°(6分钟)→+46°(1小时)→52.3°细胞培养基组分。
Application
β-Lactose has been used:
to treat HL-1 cells followed by phorbol dibutyrate (PDB) treatment to study if protein kinase C (PKC) -stimulated accumulation is mediated through galectin-3
as a component of a media to analyze the extracellular production of protein
along with recombinant galectin-3 to treat cells for the detection of galectin-3 cell surface binding
along with recombinant galectin-3 or a control protein to stimulate T cells for apoptosis assay
