不同的氨基酸带有不同化学性质的侧链基团,有的带有碱性侧链,有的带有酸性侧链,由此组成的蛋白质具有不同数目的碱性基团和酸性基团,这些基团会使蛋白质在不同的pH溶液中带有不同的净电荷,整个蛋白质分子带正电荷多,即为碱性蛋白(等电点偏向酸性);整个蛋白质带负电荷多,即为酸性蛋白质(等电点偏向酸性)。
酸性固绿染色液是利用酸性蛋白质与带有正电荷的酸性染料固绿结合进行染色,细胞中含量最为丰富的酸性蛋白主要存在于细胞质和核仁中,因此染色后细胞质和核仁大部分被染成绿色。该染色液仅用于科研领域,不宜用于临床诊断或其他用途。

临用前,取A、B等量混合,即为0.1%酸性固绿染色液。
自备材料:
1、玻片
2、70%乙醇
3、酸性分化液
4、水浴锅
5、显微镜
操作步骤(仅供参考):
1、取新鲜血液滴于载玻片一端,推片,室温晾干。
2、涂片浸入乙醇中固定,室温晾干。
3、涂片浸入酸性分化液中,水浴。
4、流水充分水洗,滤纸吸去残留水分。
5、涂片浸入酸性固绿染色液染色。
6、流水冲洗,室温晾干。
7、直接镜检或滴加1滴中性树胶,加盖盖玻片进行封片观察。
染色结果:
细胞质、核仁:绿色
细胞核大部分区域:不着色
注意事项:
1、血液涂片或骨髓涂片应厚薄均匀,以免影响染色效果。
2、血细胞涂片染色要求新鲜全血或EDTA抗凝血。
3、酸性分化液孵育后,冲洗应彻底,否则会干扰固绿的染色。
4、染色过深可用甲醇或酒精适当脱色,最好不复染。
5、pH值对染色有一定影响,载玻片应清洁、无酸碱污染,以免影响染色效果。
6、为了您的安全和健康,请穿实验服并戴一次性手套操作。

Different amino acids carry side chain groups of different chemical properties, some with basic side chains and some with acidic side chains. The proteins composed of them thus have different numbers of basic and acidic groups. These groups cause the protein to carry different net charges in solutions of different pH values. A protein with a net positive charge is defined as a basic protein (with an isoelectric point biased toward the acidic range). A protein with a net negative charge is defined as an acidic protein (with an isoelectric point biased toward the acidic range).
Acid Fast Green Staining Solution works based on the binding between acidic proteins and the positively charged acidic dye Fast Green. The most abundant acidic proteins in cells are mainly located in the cytoplasm and nucleoli. Therefore, most of the cytoplasm and nucleoli are stained green after staining. This reagent is for research use only and is not suitable for clinical diagnosis or other purposes.
Product Components and Storage Conditions:
| A1511551 | Component | 2×50mL | Storage |
| A1511551A | Acid Fast Green A | 50mL | RT |
| A1511551B | Acid Fast Green B | 50mL | RT |
Immediately before use, mix equal volumes of Solution A and Solution B to obtain 0.1% Acid Fast Green Staining Solution.
Materials Required (User-supplied):
1. Glass slides
2. 70% ethanol
3. Acid differentiation solution
4. Water bath
5. Microscope
Protocol (For Reference Only):
1. Place a drop of fresh blood on one end of a glass slide, spread into a smear, and air-dry at room temperature.
2. Immerse the smear in ethanol for fixation, then air-dry at room temperature.
3. Immerse the smear in acid differentiation solution and incubate in a water bath.
4. Wash thoroughly with running water, and absorb residual moisture with filter paper.
5. Immerse the smear in Acid Fast Green staining solution for staining.
6. Rinse with running water and air-dry at room temperature.
7. Examine microscopically directly, or add 1 drop of neutral balsam and cover with a coverslip for mounting and observation.
Staining Results:
Cytoplasm, nucleoli: Green
Most regions of the cell nucleus: Unstained
Precautions:
1. Blood smears or bone marrow smears should be of uniform thickness to avoid affecting the staining result.
2. Fresh whole blood or EDTA anticoagulated blood is required for blood cell smear staining.
3. After incubation in acid differentiation solution, thorough rinsing is necessary; otherwise, it will interfere with Fast Green staining.
4. If overstained, appropriate decolorization can be performed with methanol or ethanol; restaining is not recommended.
5. pH value has a certain influence on staining. Glass slides should be clean and free from acid or alkali contamination to avoid affecting the staining result.
6. For your safety and health, please wear a lab coat and disposable gloves during operation.
7. This product is for research use only, strictly prohibited for other purposes.
