Citraconic anhydride (Methylmaleic anhydride) is a derivative of maleic anhydride (HY-Z0060) and novel antigen retrieval solution. Citraconic anhydride reversibly blocks protein amino groups, stabilizing specific enzymes and improving their catalytic performance. Citraconic anhydride reacts with free amino groups on proteins (especially lysine residues), converting positively charged NH3 + into carboxyl groups, thereby disrupting methylene bridge crosslinks caused by Formaldehyde during antigen retrieval. Citraconic anhydride functionalizes Isotactic polypropylene. Citraconic anhydride precisely responds to pH changes to achieve reversible modification. Citraconic anhydride is irritating to skin and eyes .

Toluidine blue (ZnCl2) is a basic thiazine dye commonly used as a biological stain for microscopy. It has a deep bluish-purple color and is commonly used to stain nucleic acids such as DNA and RNA, as well as to stain mast cells, cartilage, and other connective tissues. Toluidine blue (ZnCl2) stains the acidic components of these tissues, such as sulfated or carboxylated mucopolysaccharides. It is frequently used in histology, cytology, and pathology applications to aid in the diagnosis of various diseases and conditions. The dye is usually applied to tissue sections prior to microscopic examination and can be differentiated using an acidic alcohol solution. Toluidine blue (ZnCl2) is a relatively simple and inexpensive stain with good reproducibility, making it a popular choice for many laboratories.

Sudan IV (Standard) (Solvent Red 24 (Standard)) is the analytical standard of Sudan IV (HY-D0932). This product is intended for research and analytical applications. Sudan IV is an agonist of the aryl hydrocarbon receptor (AhR) that activates downstream signaling pathways and induces CYP1A1 expression. Sudan IV promotes CYP1A1 gene transcription by activating AhR-ARNT heterodimers and binding to exogenous response elements (XREs) on DNA, thereby enhancing drug metabolizing enzyme activity. Sudan IV can be used to study the toxicity mechanisms of industrial dyes and the effects of interactions with serum proteins (such as bovine serum albumin (BSA)) on their distribution in vivo. Sudan IV is a fat-soluble diazo dye that can be used to stain lipids, triglycerides, and lipoproteins on frozen sections.

Citraconic anhydride (Methylmaleic anhydride) is a derivative of maleic anhydride (HY-Z0060) and novel antigen retrieval solution. Citraconic anhydride reversibly blocks protein amino groups, stabilizing specific enzymes and improving their catalytic performance. Citraconic anhydride reacts with free amino groups on proteins (especially lysine residues), converting positively charged NH3 + into carboxyl groups, thereby disrupting methylene bridge crosslinks caused by Formaldehyde during antigen retrieval. Citraconic anhydride functionalizes Isotactic polypropylene. Citraconic anhydride precisely responds to pH changes to achieve reversible modification. Citraconic anhydride is irritating to skin and eyes .
