分化作用是指组织染色后用某些特定的溶液将组织过多结合的染色剂脱去,这个过程称为分化作用,所用的溶液称为分化液。在HE染色和其他染色中常用1%盐酸乙醇作为分化液,因酸能破坏苏木素的醌型结构,使组织与色素分离而退色,再进行伊红染色,才能保证细胞核与细胞浆染色的分明。
盐酸乙醇分化液主要由盐酸、乙醇、去离子水等组成,经常用于苏木素染色、苏木素伊红染色 (HE染色)或Masson染色等涉及苏木素染色时,可缓慢地降低细胞浆等背景性的苏木素染色并使细胞核苏木素染色更清晰的溶液,是一种非常重要的辅助试剂。使用本产品可获得更好的苏木素染色效果。本产品的基本原理是在酸性条件下,可以有效洗去细胞核以外的苏木素染色,从而降低背景;同时,也可以使细胞核着色过深的区域染色适当减弱,使染色更清晰。
盐酸乙醇快速分化液分化时间比较短,一般需要5~15秒左右。如果希望更快速地分化,可以考虑选购盐酸乙醇超快速分化液,或用1%酸性乙醇分化液。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

Differentiation refers to the process of removing excess stain bound to tissues using specific solutions after tissue staining. The solution used in this process is called a differentiation solution. In HE staining and other staining methods, 1% hydrochloric acid-ethanol is commonly used as a differentiation solution. Acids can disrupt the quinone structure of hematoxylin, separating tissues from the pigment and causing discoloration. Subsequent eosin staining ensures clear differentiation between cell nuclei and cytoplasm.
Hydrochloric acid-ethanol differentiation solution mainly consists of hydrochloric acid, ethanol, and deionized water. It is frequently used in hematoxylin staining, hematoxylin-eosin staining (HE staining), Masson staining, and other procedures involving hematoxylin. As a crucial auxiliary reagent, it can slowly reduce background hematoxylin staining in structures like cytoplasm while enhancing the clarity of hematoxylin staining in cell nuclei. Using this product ensures better hematoxylin staining results. Its basic principle is that under acidic conditions, it can effectively remove hematoxylin staining outside cell nuclei to reduce background. Meanwhile, it can appropriately lighten over-stained areas of cell nuclei, resulting in clearer staining.
The differentiation time of Rapid Hydrochloric Acid-Ethanol Differentiation Solution is relatively short, generally about 5 to 15 seconds. If faster differentiation is required, Ultra-Rapid Hydrochloric Acid-Ethanol Differentiation Solution or 1% Acidic Ethanol Differentiation Solution can be selected. This reagent is for research use only and not intended for clinical diagnosis or other applications.
Materials to Be Prepared by the User
1. Tap water or distilled water, 4% paraformaldehyde or neutral formalin fixative, xylene or wax-immersion dewaxing and clearing solution
2. A series of ethanol solutions, hematoxylin staining solution, eosin staining solution, bluing solution (e.g., dilute ammonia water, lithium carbonate solution), and neutral balsam
Operating Procedures (HE Staining Steps, for Reference Only)
1. Dewax the tissue to water.
2. Stain with hematoxylin staining solution for 3-8 minutes.
3. Rinse with tap water or distilled water for 5-10 seconds.
4. Differentiate with Hydrochloric Acid-Ethanol Fast Differentiation Solution for 5-15 seconds.
5. Rinse with tap water for 20-30 seconds.
6. Blue the tissue with bluing solution for 20-40 seconds or with warm water for 10 minutes.
7. Dehydrate with 80% ethanol for 30-60 seconds.
8. Stain with alcoholic eosin staining solution for 20-60 seconds.
9. Dehydrate with gradient ethanol solutions, clear with xylene or environment-friendly dewaxing and clearing solution, mount the slide with neutral balsam, and examine under a microscope.
Precautions
1. The required differentiation time varies depending on different samples and staining requirements. For first-time use, it is recommended to test different differentiation times and determine the optimal duration based on microscopic observations.
2. Post-staining differentiation is an optional step, but it improves the clarity of nucleus-cytoplasm staining and enhances the visibility of nuclear membranes and chromatin morphology.
3. This product is volatile; store it in a sealed container. To avoid reduced effectiveness due to volatilization, use it as soon as possible after opening.
4. This product is corrosive. Operate with caution and take effective protective measures to avoid direct contact with the human body or corrosion of other items.
5. For your safety and health, wear a lab coat and disposable gloves during operation.
6. Use the reagent as soon as possible after opening to prevent adverse effects on subsequent experimental results.
