Testis-specific histone H1t is truly a testis-specific variant and not a meiotic-specific variant

Immunoblotting studies using highly specific polyclonal anti-histone H1t-IgG, which was extensively characterized by us previously, did not produce a signal with any of the histone H1 subtypes of either 1-day-old or adult rat ovarian nuclei. The absence of histone H1t in ovarian nuclei was also confirmed by indirect immunofluorescence studies. It is concluded, therefore, that histone H1t is truly a testis-specific histone variant and not a meiotic-specific variant.
