Ultrastructure of a fragment of T. castaneum karyosphere capsule in the stage 7 oocyte (a) and a fragment of karyosphere after immunogold labeling with anti-DNA antibody (b). In the karyosphere capsule, electron dense ‘the shell material’ (sh) and fibrillar ‘the strands’ (st) as well as the entangled filamentous material (efm) of medium electron density are distinguished; several nuclear bodies (nb) are located in the vicinity of the capsule (a). Condensed chromatin clumps (ch) and perichromatin region containing diffuse DNA loops are labeled with anti-DNA antibody; karyosphere capsule (kc) is devoid of the labels (b). Bars represent 5 μm in A and 0.5 μm in B
