Abstract
A protocol for recovered nuclear halos from insect polytene nuclei after the extraction of the nuclear proteins using LIS detergent is reported in this work. Analysis was carried out using fluorescence and confocal laser scan microscopy. The extraction of nuclear halos was possible only with nuclei-fraction isolation in hypotonic buffer without spermine and spermidine. The recovered nuclear halos from Bradysia hygida salivary gland polytene nuclei, contributed greatly to the study of the structure and function of these special organelles.
