概述

  正常情况下,与精核DNA结合的碱性蛋白(核蛋白)将经历从组蛋白到鱼精蛋白的自然成熟过程,这种成熟后的鱼精蛋白对精子基因(DNA)具有特殊保护作用,组蛋白被鱼精蛋白逐渐取代的过程称之为精子核蛋白组型转换,这种组型转换具有重要的生理意义。精子核携带着全部来自父方的遗传信息,这些基因必须在受精后才能开始表达,受精前精子基因在鱼精蛋白的特殊保护下,紧密浓集,无任何DNA转录作用,但当核蛋白组型转换异常可引起男性不育或胚胎早期夭折流产,其机理为:①精子DNA不稳定且易受损伤而难以受孕;②一旦受精,由于核蛋白组型异常,精子核不能正常解聚,从而影响了雌雄原核的融合;③胚胎不能正常发育,造成胚胎夭折而流产。因此,组蛋白的多少是精子成熟度的一个重要指标。

精子核蛋白染色液(苯胺蓝法)的作用原理是酸性条件下,苯胺蓝能特异地与精子核组蛋白富含的赖氨酸残基结合生成紫蓝色化合物,根据着色的深浅来判断精子的成熟程度。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

自备材料:

1、蒸馏水、新鲜精液样本、梯度乙醇、二甲苯或环保脱蜡液、环保透明液、中性树胶

2、(自备试剂) 伊红染色液、洗脱液

3、EP管、吸管或移液器、离心机、恒温箱、防脱载玻片

操作步骤(仅供参考):

1、配制洗涤工作液: 取适量的10×浓缩洗涤液,以蒸馏水10稀释后即为洗涤工作液。

2、取新鲜精液标本置于恒温箱37℃或常温放置,至完全液化。

3、取上述液化精液0.2~0.5ml置于EP管,再加入1~1.5ml洗涤工作液,用吸管或移液器反复吹打数次,室温2000rpm离心5min,弃去上清液,保留管底精子沉淀团,重复该操作3次。

4、向第3步的EP管中加入洗涤工作液约0.1~0.2ml,制成混合精子悬液。

5、取上述已制备好的精子悬液15μl,均匀涂布于防脱载玻片上,自然干燥。

6、在涂有待测精子的涂片区内滴加固定液2~3滴,室温固定5~15min,蒸馏水冲洗5~10min,并甩去多余水分。

7、在涂片区内滴加苯胺蓝染色液2~4滴,室温染色5min,蒸馏水冲洗5min,并甩去多余水份。

8、(备选方案)将载玻片竖直插入已盛有洗脱液的反应池中,使待测标本涂片区完全浸没于洗脱工作液中,室温处理2~5min。蒸馏水冲洗1-5min,并甩去多余水分。在涂片区内滴加复染液2~4滴,室温染色2~5min,蒸馏水冲洗1~5min。

9、迅速吹干玻片,镜检,如果需要长久保存样本,可将玻片依次置于70%、80%、95%和100%乙醇中各2min,二甲苯或脱蜡透明液透明,中性树胶封片。

染色结果:

含不成熟核蛋白的精子:紫蓝色或深蓝色

含成熟核蛋白的精子:浅蓝色或无色 (用伊红复染后为红色)

注意事项:

1、蒸馏水冲洗载玻片时要注意控制水流速度,以免洗脱涂片区内的精子。

2、滴加染液时应完全覆盖涂片区域,并用吸管吹匀。

3、甩去多余水分应防止涂片干燥。

4、为了您的安全和健康,请穿实验服并戴一次性手套操作。

  Under normal conditions, the basic proteins (nuclear proteins) bound to sperm nucleus DNA undergo a natural maturation process from histones to protamines. The mature protamines provide special protection for sperm genes (DNA). The gradual replacement of histones by protamines is referred to as sperm nucleoprotein transition, which has important physiological significance. The sperm nucleus carries all the paternal genetic information, and these genes can only be expressed after fertilization. Before fertilization, sperm genes are tightly condensed under the special protection of protamines, with no DNA transcription. However, abnormal nucleoprotein transition can lead to male infertility or early embryonic death and miscarriage. The mechanisms are as follows: ① Sperm DNA becomes unstable and susceptible to damage, making conception difficult; ② Once fertilized, the sperm nucleus cannot decondense normally due to abnormal nucleoprotein transition, thus interfering with the fusion of male and female pronuclei; ③ The embryo fails to develop normally, resulting in embryonic death and miscarriage. Therefore, the amount of histones serves as an important indicator of sperm maturity.

  Sperm Nucleoprotein Staining Solution (Aniline Blue Method). Under acidic conditions, aniline blue can specifically bind to lysine residues rich in sperm nuclear histones to form a violet-blue compound. The maturity of spermatozoa is judged by the intensity of staining.This reagent is for research use only and is not intended for clinical diagnosis or other purposes.

Materials Required:

1. Distilled water, fresh semen sample, graded ethanol, xylene or eco-friendly dewaxing solution, eco-friendly clearing solution, neutral balsam

2. (User-supplied reagents) Eosin staining solution, destaining solution

3. EP tubes, pipettes or pipettors, centrifuge, incubator, adhesive microscope slides

Protocol (For Reference Only):

1. Prepare working wash solution: Dilute the 10× concentrated wash buffer with distilled water at a ratio of 1:10 to obtain the working wash solution.

2. Place the fresh semen sample in an incubator at 37 °C or at room temperature until completely liquefied.

3. Transfer 0.2–0.5 mL of the liquefied semen into an EP tube, add 1–1.5 mL working wash solution, and mix gently by repeated pipetting. Centrifuge at 2000 rpm for 5 min at room temperature, discard the supernatant, and retain the sperm pellet at the bottom. Repeat this step 3 times.

4. Add approximately 0.1–0.2 mL working wash solution to the EP tube from Step 3 to prepare a mixed sperm suspension.

5. Take 15 μL of the prepared sperm suspension and spread evenly onto an adhesive microscope slide; allow to air-dry.

6. Add 2–3 drops of fixative solution onto the sperm smear, fix at room temperature for 5–15 min, rinse with distilled water for 5–10 min, and discard excess water.

7. Add 2–4 drops of aniline blue staining solution onto the smear, stain at room temperature for 5 min, rinse with distilled water for 5 min, and discard excess water.

8. (Optional) Insert the slide vertically into a reaction vessel containing destaining solution, fully immersing the smear area. Incubate at room temperature for 2–5 min. Rinse with distilled water for 1–5 min and discard excess water. Add 2–4 drops of counterstain onto the smear, stain at room temperature for 2–5 min, then rinse with distilled water for 1–5 min.

9. Dry the slide quickly and examine microscopically. For long-term preservation, dehydrate the slide sequentially in 70%, 80%, 95%, and 100% ethanol for 2 min each, clear in xylene or dewaxing/clearing solution, and mount with neutral balsam.

Staining Results:

Sperm with immature nucleoprotein: violet blue or dark blue

Sperm with mature nucleoprotein: light blue or colorless (red after eosin counterstaining)

Precautions: 

1. When rinsing the slides with distilled water, control the flow rate carefully to avoid washing off the sperm on the smear area.

2. When adding the staining solution, ensure it fully covers the smear area and mix evenly by pipetting.

3. After discarding excess water, prevent the smear from drying out.

4. For your safety and health, please wear a lab coat and disposable gloves during operation.
