Terephthalaldehyde	Drug Intermediate Biochemical Assay Reagents	Others
Terephthalaldehyde is a crosslinking agent. Terephthalaldehyde forms a crosslinked structure inside the gelatin matrix by forming Schiff base imines with the amino groups of gelatin, thereby constructing a three-dimensional network. Terephthalaldehyde improves the hydrophobicity of the gelatin matrix, delays water vapor penetration and enhances the liquid water resistance of gelatin films. Terephthalaldehyde can be used as a crosslinking agent to prepare crosslinked chitosan hydrogel (CAAT) via ultrasound-induced synthesis. Terephthalaldehyde helps CAAT hydrogels selectively adsorb anionic dyes from aqueous media, including multi-component systems containing cationic dyes. Terephthalaldehyde serves as a starting material for the synthesis of bis-heterocyclic compounds (including bis-thiazole and bis-triazolopyrimidine compounds) .

Weigert Elastin Staining Kit
MCE Weigert Elastin Staining Kit combines Weigert Resorcinol Fuchsin Staining Solution with Van Gieson (VG) Staining Solution. Weigert Resorcinol Fuchsin Solution is mainly used for staining elastic fibers, Van Gieson (VG) Solution is used for collagen fiber staining. The principle of VG staining is based on differences in the size of anionic dye molecules and the permeability of tissues. Picric acid (PA) has the smallest molecular weight and preferentially enters dense structures. Ponceau Red or acid fuchsin has a relatively larger molecular weight and primarily binds to collagen fibers, while light green has the largest molecular weight and stains other tissue components. After VG staining, collagen fibers appear red, while muscle fibers and cytoplasm appear yellow, enabling a clear distinction between tissue components.
