Histological Staining

Tissue and Cell Fixative (4% Paraformaldehyde, PFA) is mainly composed of paraformaldehyde, phosphate, and deionized water, with a pH of 7.0-7.4. Tissue and Cell Fixative (4% Paraformaldehyde, PFA) is suitable for fixing most tissues and cells, and can effectively protect the morphology and structure of tissues and cells as well as nucleic acids.

Glutaraldehyde Fixative (2.5%, For Electron Microscopy) is composed of glutaraldehyde, phosphate, deionized water, etc., with a pH range of 7.2-7.4. This fixative is effective in fixing fine structures of cell nuclei and cytoplasm and is commonly used for fixing electron microscopy specimens.

X-GAL (BCIG) (solution) is a widely used chromogenic β-galactosidase substrate. X-GAL is a colorless compound until cleaved by β-galactosidase, at which point X-GAL turns to an insoluble and detectable blue compound, making X-GAL particularly useful in techniques such as blue-white screening for cloning in bacteria. X-GAL can also be used for detection of β-galactosidase activity.
Solvent and Concentration: DMF: 20 mg/mL

Crystal Violet (solution) , also known as Gentian violet, methyl violet 10B, is a triphenyl-methane, an alkaline dye that binds to DNA in the nucleus of a cell, staining it a deep purple. It is often used for Gram staining to classify bacteria, or for cell or histological staining.
Solvent and Concentration: Sterile water: 5 mg/mL (0.5%)

Frozen Section Embedding Medium is a water-soluble mixture of polyethylene glycol and polyvinyl alcohol, widely used in immunohistochemistry experiments. Frozen Section Embedding Medium supports tissue during frozen sectioning, increasing tissue continuity and reducing wrinkling and fragmentation.

Thioflavin T (solution) is a cationic Benzothiazole dye that shows enhanced fluorescence upon binding to amyloid in tissue sections. Excitation max.: ~385 nm (free) ; ~450 nm (bound) ; Emission max.: ~445 nm (free) ; ~485 nm (bound) .
Solvent and Concentration: Sterile water: 10 mM
The 1 mL volume is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

Methoxy-X04 (solution) is a fluorescent dye that crosses the blood-brain barrier and selectively binds to beta-pleated sheets found in dense core amyloid Aβ plaques. Methoxy-X04 retains in vitro binding affinity for amyloid b (Ab) fibrils (K_i= 26.8 nM). Methoxy-X04 is fluorescent and stains plaques, tangles, and cerebrovascular amyloid in postmortem sections of AD brain with good specificity.
Solvent and concentration: DMSO: 5 mg/mL

Texas Red (Sulforhodamine 101) (solution) is an amphoteric rhodamine red fluorescent dye (excitation/emission: 586/605 nm). Texas Red is used extensively for investigating neuronal morphology and acts as acell type-selective fluorescent marker of astrocytes bothin vivoand in slice preparations.
Solvent and concentration: DMSO: 10 mM
The 1 mL volume is defined as the base specification. All larger sizes correspond to incremental volumes of this base.
