Histological Staining
Lignin Staining Solution (Safranin Method) is a histochemical staining solution for lignin with Safranin O as the active component. Lignin Staining Solution (Safranin Method) enables lignified cell walls to appear red to deep red (pinkish in regions with low lignification) via the high affinity of the dye for lignin. Lignin Staining Solution (Safranin Method) can be used to visualize lignin distribution in ex vivo thick sections of annual shoots from woody plants and vibratome sections of stems from herbaceous plants (such as Arabidopsis and flax), as well as for in situ quantification of cell wall substructural regions (cell corners, intercellular layers, secondary walls) based on Safranin O ratiometric fluorescence.
Cellulose Staining Solution (Zinc Chloride-Iodine Method) is a cellulose-targeted staining agent. Cellulose Staining Solution (Zinc Chloride-Iodine Method) enables cellulose cell walls to turn blue-purple to blue by forming iodine-cellulose complexes between iodine and cellulose. Cellulose Staining Solution (Zinc Chloride-Iodine Method) can be used for the identification of plant phloem fibers, cellulose layers of algal cell walls, residual mineralized plant fibers from archaeological samples, and cellulose deposited on PET surfaces.
Ruthenium Red Staining Solution (0.01%) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium Red Staining Solution (0.01%) strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium Red Staining Solution (0.01%) is a L-type calcium current (ICa) blocker. When using Ruthenium Red Staining Solution (0.01%) to stain plant tissue sections affected by pathogens, the breakdown of mucilaginous substances by the pathogens prevents them from taking up the stain, whereas the cell walls of healthy tissue stain red.
Methyl Green Staining Solution (Chloroform-Extracted, 1%) is a basic dye stock solution with differential nucleic acid binding activity that distinguishes double-stranded DNA from RNA, and it can be used for assays related to nucleic acid distribution and DNA localization. Methyl Green Staining Solution (Chloroform-Extracted, 1%) functions by competitively binding to the phosphate groups of nucleic acids and stably binds to intact double-stranded DNA; RNA within the oocyte-specific ribonucleoprotein complex specifically binds to this dye, and RNase completely blocks this binding reaction. The nucleic acid recognition of Methyl Green Staining Solution (Chloroform-Extracted, 1%) depends on the size of the dye cation and the intact double-helical structure of DNA.
Dienes Mycoplasma Staining Solution is a Romanovsky type absorbent composite staining solution, containing Methylene Blue (HY-14536) and Azure II (HY-D0946). Dienes Mycoplasma Staining Solution is used for identifying mycoplasma colonies growing on solid agar, or for staining fixed cell cultures and tissue sections. Dienes Mycoplasma Staining Solution can distinguish between tiny cell-free bacteria and ordinary bacterial colonies under an optical microscope.
Ehrlich's Reagent is an indicator with p-dimethylaminobenzaldehyde (HY-Y0015) as its core component. Ehrlich's Reagent is mainly used for the identification of enterobacteria, non-fermentative bacteria, fastidious bacteria and anaerobic bacteria, as well as the detection of indole derivatives and amines. It turns pink, red or purple when a positive reaction occurs. Ehrlich's Reagent undergoes colorimetric reactions with urobilinogen, indican, phenol, allantoin, tryptophan and uric acid, and forms yellow-green products when reacting with sulfur derivatives.
Ready-to-Use Wright Staining Solution is a pre-mixed Romanowsky type absorbent composite staining agent, containing Eosin Y (HY-D0505) and methylene blue (HY-14536). Ready-to-Use Wright Staining Solution is suitable for staining of blood and cell smears, bacteria, protozoan parasites, etc., without the need for manual weighing of powder or complex preparation, thus saving time and ensuring the consistency of diagnostic results.
Ready-to-Use Giemsa Staining Solution is a ready-to-use Romanowsky-type staining solution that can be used for staining blood and cell smears, bacteria, chromosome banding, parasites, and other specimens. Ready-to-Use Giemsa Staining Solution stains blood smears to reveal blood parasites including Plasmodium, microfilariae, and trypanosomes. Ready-to-Use Giemsa Staining Solution enables morphological identification of blood cells, and can also stain fixed cells to observe muscle cell nuclei, distinguish myotubes from myoblasts, and quantitatively analyze the differentiation status of myoblasts.
Nissl Staining Solution (Thionin Method) is a neural tissue staining solution with thionin as the core component, which stains Nissl bodies purplish blue and nuclear chromatin blue. Nissl Staining Solution (Thionin Method) relies on positively charged thionin molecules to specifically bind to the negatively charged nucleic acid components in the rough endoplasmic reticulum inside Nissl bodies, and achieves differential staining by regulating pH through a buffer system. Nissl Staining Solution (Thionin Method) has pH-dependent staining selectivity; it exhibits the highest staining specificity for neuronal Nissl bodies under pH 3.65 conditions, and can efficiently label glial processes under pH 4.6 conditions.
Nissl Staining Solution (Toluidine Blue Method) is an acidic histological staining labeling reagent based on Toluidine Blue (HY-D0220). Nissl Staining Solution (Toluidine Blue Method) stains brain nuclei, cells, and sections of brain tissues processed for in vitro autoradiography or perfusion. It consistently labels all neuronal somata and differentiates cell layers.
Luxol Fast Blue Staining Solution is a copper phthalocyanine-based histological dye that specifically binds to lipid-rich structures such as myelin sheaths and mitochondria, staining them blue-green. Luxol Fast Blue Staining Solution is suitable for displaying myelin sheaths in neural tissues, staining mitochondria in tissues such as kidney/liver, and staining sections for phase contrast microscopy. It is often used in combination with PAS, Phloxine or Cresyl Violet to enhance structural contrast.
0.5% Evans Blue Staining Solution is an azo dye solution that strongly binds to serum albumin to form a high-molecular-weight tracer complex. 0.5% Evans Blue Staining Solution can passively leak with albumin and produce color when the blood-brain barrier or vascular barrier is damaged in vivo, and it is used for permeability assessment. 0.5% Evans Blue Staining Solution is excluded by living cells but enters dead cells to stain them in vitro due to the loss of membrane integrity in dead cells. 0.5% Evans Blue Staining Solution can be used for studies related to the identification of dead/necrotic cells and blood-brain barrier (BBB) permeability.
Congo Red Staining Solution (1%) is an absorptive histochemical staining solution based on Congo Red (HY-D0236), which is specifically designed to detect amyloid deposits in tissue sections. When observed under a polarizing microscope, the stained amyloid complexes exhibit characteristic apple-green birefringence, making it a standard tool for the diagnosis of amyloidosis.
Eosin-Nigrosin Sperm Viability Staining Solution is a differential viability staining solution used to distinguish live/dead sperm and other cells, consisting of Eosin Y (HY-D0505) and Nigrosin (HY-W250145). Eosin-Nigrosin Sperm Viability Staining Solution cannot penetrate the membrane of live cells; it stains dead cells dark pink and uses nigrosin to form a contrasting dark background. Eosin-Nigrosin Sperm Viability Staining Solution can distinguish live sperm, dead sperm and sperm with neck leakage, and can stain dead sperm or sperm affected by excessive microbial growth.
Neutral Red Staining Solution (for Live Cells) is a vital stain used for vital staining of peripheral blood cells, and it can also be used for staining other living cells or tissues. Neutral Red Staining Solution (for Live Cells) accumulates in cytoplasmic vacuoles, lysosomes of living cells, as well as plant/fungal vacuoles. It binds to anionic sites, suberin, lignin, cell walls, DNA and phenolic substances, and can intercalate into DNA. Neutral Red Staining Solution (for Live Cells) stains the cytoplasm of specific phytoplankton and estuarine zooplankton, while dead cells are not stained, enabling viability determination of such organisms.
