We successfully reproduced the transient toluidine blue staining reported by Hirschman and McCabe to compare it with DAPI staining of polyP in the growth plate.
In Nodal-lacZ heterozygous embryos of 5 12 somites, β galactosidase staining reported robust Nodal expression around the node and in the left LPM of wild type embryos (n = 32) whereas compound Nodal-lacZ heterozygous, Tbx6 mutant embryos equivalent to 3 10 somite stages as judged by head morphology showed only modest expression around the node and no expression in the LPM (n = 8)(Figure 2E,F).
This is the first triple immunochemical staining reported using thyroid cytologic preparations and histology tissue.
Previous studies using DTT-treated sperm and toluidine blue staining reported increased metachromatic staining in infertile patients [ 28, 29].
There is ample documentation of iron staining reported on the teeth of children taking iron syrups, drops and other preparations [ 5, 8– 10].
There were no adverse effects reported by participants in the study except for those referring to unpleasant taste and teeth staining reported by some participants who dropped out of the study.
One study, using this antibody for IHC staining, reported that sections of heart and kidney were just as reliable for the diagnosis of WNV infection as RT-PCR performed on fresh brain tissue in AMCRs.
Based on the differential pattern of cytokeratin staining reported in the literature, we decided to evaluate the cytokeratin expression in tissue samples of lung and colorectal adenocarcinomas, obtained from our patient population.
The cut-off values of high GPC3 expression were 0% [ 26], 10% [ 18, 20, 23, 24], 20% [ 19], and 25% [ 25] of positive tumor cells by IHC staining reported in the included studies, respectively (Table 1).
For the Hoechst staining reported in Figure S2, dissected gonads were incubated in 5 µM Hoechst dye (Hoechst 33343; Invitrogen) in dark for 2 hr, followed by washing with M9 buffer.
