邻硝基苯-β-吡喃半乳糖苷 O-nitrophenyl-β-D-galactopyranoside
缩写为 ONPG。是广泛利用于β -半乳糖苷酶活力测定的底物。水解后可游离出邻硝基酚,由于邻硝基酚在碱性条件下呈黄色( 420毫微米光吸收),所以容易进行比色定量。另外利用这种性质,还可用于分离各种代谢调节突变株。
Synthesis of Azido-Functionalized Carbohydrates for the Design of Glycoconjugates
of the carbohydrate derivative, or attached to a spacer arm. We describe here the syntheses of 2,3,4,6-tetra-O -acetyl-β-d -glucopyranosyl azide as well as 1-azido-3,6-dioxaoct-8-yl 2,3,4,6-tetra-O -acetyl-β-d -galactopyranoside and 1-azido-3,6-dioxaoct-8-yl
Basic Methods of Culturing Drosophila
on the health and fecundity of the genotype, the temperature at which it is raised, and the density of the cultures. Temperature has a large effect on the rate of Drosophila development. Generation time (from egg to adult) is approximately: 7 days at 29o C
