组织固定液由10%~15%福尔马林溶液、1%~5%磷酸盐缓冲溶液和纯化水组成。用于新鲜组织样本的固定。
检验原理:醛类固定液是一种交联性组织固定剂,主要通过使蛋白质分子发生交联而产生固定作用,本品用磷酸盐缓冲液调节溶液pH值,使其成中性,以期达到大限度地保护组织抗原,固定效果及对组织抗原性的保存均优于一般的甲醛溶液,是生物组织常用的固定液。
使用方法:
1、打开固定溶液器的盖子,将生物组织标本放入10%中性缓冲福尔马林固定液中。
2、固定液量应为标本体积的5~10倍;将离体组织及时 (一般不超过3分钟),浸入组织固定液中,标本固定时间为2~12小时。
3、随机盖紧容器盖子,并在标签上记录标本信息,送病理科进行检验。
注意事项:
1、注意使用时通风。
2、一次性使用,且忌新旧液混合使用。
3、使用时避免接触皮肤、粘膜。
4、只用于标本前处理。
5、本试剂仅专业人士使用,使用前请认真阅读使用说明书,在有效期内使用,并做好个人防护。
6、使用后的固定液应该按照病理科实验室的试剂使用规范进行无害化处理。
7、储存条件:4℃~40℃通风良好、防潮、阴凉处存放;远离热源、火花与明火;运输及搬运时小心轻放,防止挤压。开封后3个月内使用完,每次用后及时拧紧瓶盖,以免挥发或变质。
Tissue fixative consists of 10%–15% formalin solution, 1%–5% phosphate buffer solution and purified water. It is used for the fixation of fresh tissue samples.
Test Principle:
Aldehydes act as cross-linking tissue fixatives. They achieve fixation mainly by inducing cross-linking between protein molecules. This product is adjusted to a neutral pH with phosphate buffer, which maximally preserves tissue antigens. It delivers better fixation performance and superior retention of tissue antigenicity compared with ordinary formaldehyde solutions, and is a commonly used fixative for biological tissues.
Instructions for Use:
1. Open the container cap and immerse biological tissue specimens into 10% neutral buffered formalin fixative.
2. The volume of fixative shall be 5 to 10 times that of the specimen. Place excised tissues into the fixative promptly (within 3 minutes). The fixation time ranges from 2 to 12 hours.
3. Tighten the container cap immediately, label the specimen with relevant information, and send it to the pathology department for examination.
Precautions:
1. Use the product in a well-ventilated area.
2. For single use only. Do not mix fresh and used fixative.
3. Avoid contact with skin and mucous membranes during operation.
4. Intended solely for pre-treatment of specimens.
5. This reagent is for professional use only. Read the instructions carefully before use, employ the product within its shelf life, and take proper personal protective measures.
6. Dispose of used fixative in accordance with the waste management regulations of the pathology laboratory.
7. Storage: Store at 4 °C to 40 °C in a cool, dry and well-ventilated place. Keep away from heat sources, sparks and open flames. Handle with care during transportation to avoid extrusion. Use up the product within 3 months after opening. Tighten the cap immediately after each use to prevent volatilization and deterioration.
