Immunofluorescence Stain for Genital Secretion (II) Baso Stains for Healthcare Facility What is Immunofluorescence Stain for Genital Secretion (I)? This product applies immunofluorescence technology. After binding to the corresponding antigen in the sample, it shows specific imaging under the excitation light of a specific band of a fluorescence microscope. Observe fungi under the UV band (ultraviolet excitation filter plate, excitation wavelength: 340nm-380nm), and observe

Immunofluorescence Stain for Genital Secretion (I) Baso Clear Colourful Stains What is Immunofluorescence Stain for Genital Secretion (I)? This product employs the immunofluorescence technique. After binding with the corresponding antigen in the sample, it produces specific fluorescence imaging under excitation light of designated wavelength bands in a fluorescence microscope. Bacteria, fungi, and cells are observed under Band B (violet-blue excitation filter, excitation

Trypan Blue Stain Baso Clear Colourful Stains for Medical Diagnosis What is Trypan Blue Stain? Trypan blue is a cell-reactive dye, commonly used to test cell membrane integrity to determine if cells survive. When cell damage or death, trypan blue can penetrate the denatured cell membrane into the cells, make it blue; The living cells can prevent the dye into the cell, it is not colored. In order to identify dead cells and living cells. Strictly speaking, trypan blue staining

Naphthol AS-D Chloroacetate Esterase (AS–DCE) Stain Intended Use: This kit is for staining bone marrow cell and bloodcell smear. Principle: Naphthol AS-D chloroacetate can be hydrolyzed into Naphthol AS-D by Esterase to mix with diazonium salt and form insoluble red-brown precipitate in cytoplasm. Positive reaction is only found in granulocytes; hence, it is also called "Specific Esterase Stain". Specifications: Contents 5Tests/Kit 20Tests/Kit 100Tests/Kit Components Fixative

α-Naphthyl Acetate Esterase (α-NAE) Stain Intended Use: This kit is for staining bone marrow cell and bloodcell smear. Principle: Hydrochloric acid parafuchsin reacts with Sodium Nitrite to form diazonium salt (six-azo-pararosaniline). α-Naphthyl Acetate is decomposed by esterase and produces α-naphthol, which shall combine with diazonium salt to form red brown precipitate in cytoplasm. This stain has no specificity against esterase; therefore, it is called "Non-specific

Leukocyte Peroxidase (POX) Stain (Benzidine Method) Intended Use: This kit is for staining bone marrow cell and blood cell smear. Principle: Benzidine method: Intracellular peroxidase can let the colorless diamino benzidine hydrogen atom transfer to hydrogen peroxide. The former becomes colored dye deposited on where the cytoplasmic enzyme location.
