General description

Cell-permeable DNA-binding dye. Binds preferentially to DNA rich in adenine and thymine. Used in flow cytometry for measuring nuclear DNA content or for sorting isolated chromosomes. Useful for microscopic detection of nuclei and nuclear DNA in normal and apoptotic cells. Can also be used to detect mycoplasma. A reversible inhibitor of S-adenosyl-L-methionine decarboxylase and diamine oxidase. Also available as a 5 mg/ml mM solution in H2O (Cat. No. 508741).
Fluorescent dye specific for DNA. Binds preferentially to DNA rich in adenine and thymidine (excitation max. = 359 nm, emission max. = 461 nm). Useful for microscopic analysis of nuclei and nuclear DNA in apoptotic cells. Can also be used to detect mycoplasma. Reversible inhibitor of S-adenosyl-L-methionine decarboxylase and diamine oxidase. Cells are typically stained at 1 µg/ml.

LentiBrite™ Lentiviral Biosensors for Fluorescent Cellular Imaging: Analysis of Autophagosome Formation

Expression of genetically-encoded fluorescently-tagged proteins has widely been employed for real-time visualization of cellular behavior and trafficking. Prepackaged, ready-to-use, high-titer lentiviral particles (which we have termed “lentiviral biosensors”) encoding GFP- or RFP-tagged proteins are a convenient, robust solution for fluorescent imaging of transduced cells. Compared to other nonviral transfection methods, lentiviral transduction, in many cases, offers higher transfection efficiency and more homogeneous protein expression, particularly for traditionally hard-to-transfect primary cell types. Lentiviral biosensors are ideal for use with fixed and live cell fluorescent microscopy, and are non-disruptive towards cellular function. GFP- or RFP-protein localization matches well with antibody-based immunostaining and demonstrates altered patterns of expression upon treatment with modulators of cell function and phenotype. Lentiviral biosensors provide a broadly effective, convenient method for visualization of cell behavior under a variety of physiological and pathological treatment conditions, in both endpoint and real-time imaging modalities. In this study, we focus on lentiviral biosensors containing GFP-LC3 and RFP-LC3 for the study of autophagosome formation.
