Fig. 2 Electron micrograph of a microspread mouse spermatocyte, stained with phosphotungstic acid. The axis of the X and Y chromosomes show a short synaptic region in the lower part of the figure. A nucleolar body (asterisk) is close to the XY pair. The autosomal bivalent (up) shows a recombination nodule (arrowhead). xSOOO.

Staining with PTA. This procedure leads to a substantial amount of information on SCs (kinetochores, LEs, attachment plaques) and on recombination nodules. Some weaknesses of PTA staining are the variability in the degree of staining, low contrast in the EM, and the requirement for fresh spreads. [Pg.243]
