I will very appreciate that if you can share with me how is it going with these Alexa Fluor conjugated secondary antibodies on Typhoon? No. Scale bar for histological images = 20 µm. Can anyone recommend a good free FACS analysing software? Does anyone do this in X. laevis for whole-mount staining? Alexa Fluor 594 dye molecules can be attached to proteins at high molar ratios without significant self-quenching, enabling brighter conjugates and more sensitive detection. For stable signal generation in imaging and flow cytometry, Alexa Fluor 594 dye is pH-insensitive over a wide molar range. All rights reserved.

Streptavidin-Alexa Fluor® 594 is useful as a second step reagent for indirect immunofluorescent staining, when used in conjunction with biotinylated primary antibodies. From various protocols I've come across, I understand that I can run the protein on a normal gel with my usual SDS sample buffer as GFP is stable enough to still fluorese, but I should not boil (which I would not do with a membrane protein anyway) or heat the samples in any way. Dye 5' Int 3' Ex. We offer Alexa Fluor 594 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection. In addition, reactive dye forms and protein labeling kits are available to allow you to generate your own antibody conjugates or probes.

Initial transfer performed overnight (16hr) at 30V failed because small and mid sized proteins (smaller than 100kDa) transferred right through the membrane (as evident from Ponceau staining of the blot and Coomassie staining of the gel). DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. I'm ordering reagents for Western blotting, the experiment will be started, I think, maybe 1 month later. How to denote letters to mark significant differences in a bar chart plot. Add your answer. The antibody was purified by affinity chromatography and conjugated with Alexa Fluor® 594 under optimal conditions. I was talking to a postdoc and they said I should wash with 0.01% Tween-20 in PBS (PBS-Tween 20), and antibody stain with 0.01% Triton X-100 in PBS (PBS-TritonX) since Tween-20 is a less harsh detergent than Triton X-100.
