Brilliant Blue R concentrate is a methanol based stain especially designed for staining protein in polyacrylamide but will also stain agarose gels. The stain contains methanol and acetic acid so gels do not require fixing prior to staining. Brilliant Blue R Concentrate has been used for protein band detection after nondenaturing gradient gel electrophoresis, isoelectric focussing and SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis). For detection of protein bands following electrophoresis.

3,3′-dihexyloxacarbocyanine iodide (DiOC6) is a supravital lipophilic fluorochrome. This cationic dye is employed to stain mitochondria and endoplasmic reticulum in animal and plant cells. In addition, it acts as a very rapid, consistent and highly selective fluorochrome for endophytic ascomycetes in plant roots and liverworts. DiOC6 also facilitates the detection of different mitochondrial changes happening during early apoptosis.
