Apexbio Technology LLC Wright Staining Solution 500ml
Wright Staining Solution composed primarily of eosin and methylene blue is frequently utilized in microscopic examination for differentiation and identification of cell types particularly in hematological analysis Its staining mechanism relies upon the differential affinity of cellular components for acidic and basic dyes eosin an acidic dye stains cytoplasmic granules and erythrocytes pink or orange-red whereas methylene blue a basic dye binds nucleic acids or acidic cellular structures to yield shades of blue or violet In practice mature erythrocytes and eosinophils stain distinctly pink lymphocytes monocytes and basophils appear dark bluish-purple and neutrophils exhibit a pale purple hue due to combined dye affinity Typical usage involves staining thin blood smears or bone marrow aspirates at undiluted formulation to facilitate morphological assessment and differentiation of cell populations
Apexbio Technology LLC Cholic acid 81-25-4 10mM (in 1mL Ethanol)
Cholic acid (CAS 81-25-4) is a naturally occurring bile acid characterized by amphipathic properties enabling it to function effectively as an ionic mild detergent under non-denaturing conditions This molecule interacts with lipid membranes altering permeability and facilitating the disruption of protein-lipid interactions without denaturing integral membrane proteins Due to this mechanism cholic acid is widely utilized in biochemical research protocols particularly for the solubilization extraction and purification of biologically active membrane proteins and receptor complexes
