With quantum dots and a modern fluorescence microscope with "channels" it should be possible to label 2 or 3 antigens simultaneously, if you have all the right primaries and labelled secondaries. The company that sells you the quantum dot labelled secondaries or other amplification reagents shou

Thank you everyone for your advice, I really appreciate it!  I am doing a multiplex immunofluorescent assay (4 channels) and I am planning to strip the antibodies and reprobe with a second round of antibodies.  The antibodies are labelled with quantum dots so I am not sure how that will influen

Hi, My respects! I wanted to do some zebrafish larvae sectioning. But some slice I made showed that the tissue inside had been broken. As to me, I thought the problem might be in dehydration time and and the razor I used. So can you please give me some advice to improve the process? In addition

Antibodies are quite easily removed by acidity - pH 1 to 2. This also removes enzyme-antibody conjugates. The coloured products of the enzyme histochemical reactions are generally not affected. The brown oxidation product of DAB (from peroxidase) and the blue products from bromochloroindoxyl/t
