BETA-D-吡喃半乳糖

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Cells were seeded on 100-mm culture dishes and treated with doxorubicin, tetrac or both for 24 h, after which the cells were subjected to trypsin treatment at 37° C. for 3 min, fixed with 4% formalin in PBS, and washed with PBS. Then they were incubated with 0.1 μg/ml Hoechst 33248 (bisbenzimide, Sigma-Aldrich) and spotted on slides for microscopy. Positive cells are counted and their fractions between non treated and treated populations are compared. at 37° C. for 3 min washed with PBS their fractions between non treated treated populations

实验步骤: β-D-galactose (10 g, 1 eq), decylamine (8.7 g, 1 eq), and water (2 g, 3eq) were heated in a reaction flask for 20 min at 80° C. Methanol/ethyl ether (50 v/50 v) was added, the product was filtered, washed with ethyl ether (2×50 ml) and dried, to give a 90% yield. the product was filtered washed with ethyl ether (2×50 ml) dried to give a 90% yield

实验步骤: To the Fab' (1 mg) prepared in the above process (a) was added the β-Gal-maleimide (3.9 mg) prepared in the process (b) and the mixture was reacted at 30° C. for 30 minutes. The reaction solution was centrifuged and the supernatant was subjected to Sepharose 6B column (φ1.5 cm×50 cm, eluent: 10 mM phosphate buffer, pH 6.5, containing 0.1% BSA) to give a β-Gal-Fab' fragment. the mixture was reacted at 30° C. for 30 minutes
