Photoactivatable fluorescent dye; supplied as an NHS ester for coupling to primary amine groups. Non-fluorescent until activated at 365 nm. Photochemical quantum yield of uncaging = 2.2%, with improved yield upon protein conjugation. NHS ester can be converted to relevant substrate for use in self-labeling tag systems, e.g. HaloTag® and SNAP-tag®. Suitable for single molecule tracking and super resolution microscopy in live cells, specifically live cell sptPALM and fixed cell PALM. Can be multiplexed with PA Janelia Fluor® 646, SE to perform two-color sptPALM in live cells with activation at 405 nm. Cell permeable. Excitation maximum = 551 - 553 nm; emission maximum = 570 - 573 nm. HaloTag is a trademark of Promega Corporation, and SNAP-tag is a trademark of New England BioLabs, Inc.

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
