General description

Bouin′s solution is a noncoagulant yellow stain fixative that consists of saturated picric acid, formaldehyde, and acetic acid.

Application

Bouin′s solution is an excellent fixative for preserving soft and delicate structures. It is used as a mordant in various trichrome procedures.
Additionally, it has been used for the following purposes-
  • staining of human liver biopsy tissue samples for two-photon excited fluorescence (TPEF) and second-harmonic generation (SHG) imaging
  • fixation of rat ovaries for the observing follicle cells using microscopy
  • fixation of gonads of crab for morphological and histological analysis
Prepared with saturated picric acid, formaldehyde and acetic acid. Excellent fixative for preserving soft and delicate structures. Used as a mordant in various trichrome procedures.

Biochem/physiol Actions

Bouin′s solution causes shrinkage of tissues when used as a preservative due to its picric acid component. It preserves morphological and nuclear information in tissues upon fixation.

Trichobilharzia species are parasitic flatworms (called schistosomes or flukes) that cause important diseases in birds and humans, but very little is known about their molecular biology. Here, using a transcriptomics-bioinformatics-based approach, we explored molecular aspects pertaining to the nutritional requirements

Spermatogenesis begins at puberty and continues throughout a male's life. This process is initiated and maintained by spermatogonial stem cells in the seminiferous tubules, and these cells produce haploid spermatozoa. Markers of male germ cells have been fully identified in

Neurotrophism, structural plasticity, learning and long-term memory in mammals critically depend on neurotrophins binding Trk receptors to activate tyrosine kinase (TyrK) signaling, but Drosophila lacks full-length Trks, raising the question of how these processes occur in the fly. Paradoxically, truncated

Despite widespread distribution of LAMP1 and the heterogeneous nature of LAMP1-labeled compartments, LAMP1 is routinely used as a lysosomal marker, and LAMP1-positive organelles are often referred to as lysosomes. In this study, we use immunoelectron microscopy and confocal imaging to
