Study of human chromosomes. IV. Labeling of chromosomal proteins with the amino group specific fluorescent reagent fluorescamineLJ Sciorra, ML Lee and H Wynnyckyj
We describe a method for labeling chromosomal proteins with an amino- group-specific fluorescent reagent, fluorescamine. Chromosomes thus labeled appear either as uniformly fluorescent or as haloes in structure depending on the proteins remaining after treatment with acid- alcohol fixation. Using fluorescamine as a probe, we demonstrate that there is a substantial loss of labeled proteins during the chromosomal preparation and also during the trypsin treatment used in the banding of chromosomes.
