果胶类物质以原果胶、果胶(Pectin)、果胶酸的形态广泛存在于植物果实、根、茎、叶中,作为细胞壁组成成分与纤维素伴生,是相邻细胞中间层的粘结物,可使植物组织细胞紧密黏结。其中原果胶为非水溶性物质,在未成熟果实或植物组织中,果胶物质多与纤维素结合以原果胶形式存在,能让植物组织坚硬、变脆,且原果胶可在酸、碱、盐等化学试剂及酶的作用下水解,转化为水溶性果胶;果胶又称多聚半乳糖醛酸,是由 D - 半乳糖醛酸以 α-1,4 糖苷键连接形成的直链状多糖聚合物,含数百至约 1000 个脱水半乳糖醛酸残基,平均相对分子质量为 50000~150000。
本产品基于氯化铁羟胺反应实现染色,染色后果胶呈红色,主要适用于新鲜植物切片、石蜡切片、徒手切片等样本的染色,该试剂仅限科研领域使用,不可用于临床诊断等其他用途。

注意事项
1. 一般石蜡切片效果不佳,切片脱蜡应尽量干净。
2. 避免使用铬酸固定剂,铬酸盐处理也会妨碍铁的保存。
3. 试剂开封后请尽快使用,以防影响后续实验效果。
Pectic substances, existing in the forms of protopectin, pectin, and pectic acid, are widely distributed in plant fruits, roots, stems, and leaves. As a cell wall component associated with cellulose, they act as the adhesive in the middle lamella between adjacent cells, contributing to the tight bonding of plant tissue cells. Among these, protopectin is water-insoluble. In unripe fruits or plant tissues, pectic substances are often bound to cellulose in the form of protopectin, lending rigidity and brittleness to the plant tissue. Protopectin can be hydrolyzed by chemical reagents such as acids, alkalis, salts, or by enzymes, converting into water-soluble pectin. Pectin, also known as polygalacturonic acid, is a linear polysaccharide polymer composed of D-galacturonic acid residues linked by α-1,4 glycosidic bonds. It contains several hundred to about 1000 dehydrated galacturonic acid residues, with an average relative molecular mass ranging from 50,000 to 150,000.
This product is based on the ferric chloride-hydroxylamine reaction for staining. After staining, pectin appears red. It is primarily suitable for staining samples such as fresh plant sections, paraffin sections, and free-hand sections. This reagent is intended for research use only and is not suitable for clinical diagnosis or other purposes.

Materials to Be Prepared by User
Procedure (For Reference Only)
1. Sectioning: Use fresh tissue sections, free-hand sections, or sections from a sliding microtome, and place them on a glass slide.
2. Enhancement: Add pre-warmed (37–45°C) Acid Enhancer Solution to cover the section. Allow it to stand at room temperature for 1-3 minutes.
3. Discard the solution and rinse briefly under running water.
4. Alkalinization: Add 250-500 μL of Alkaline Hydroxylamine Staining Solution to completely cover the section. Allow it to stand at room temperature for 5 minutes or longer.
5. Acidification: Directly add an equal amount of Acidification Solution. Allow it to stand at room temperature for 2 minutes.
6. Remove the liquid and blot dry with filter paper. Add Ferric Chloride Solution to immerse the section. Allow it to stand at room temperature for 3-8 minutes.

Notes
1. Staining results are generally suboptimal for paraffin sections. Ensure paraffin removal is as thorough as possible.
2. Avoid the use of chromic acid fixatives, as chromate treatment can also interfere with iron retention.
3. Use the reagents as soon as possible after opening to avoid affecting subsequent experimental results.
