## TL;DR

This paper introduces a new decalcification method for bone marrow biopsies that preserves tissue integrity while efficiently removing calcium.

## Contribution

A novel decalcification method using 12% formic acid and 8% hydrochloric acid is proposed for bone marrow tissue.

## Key findings

- The method effectively removes calcium without excessive tissue damage.
- It preserves antigen activity for downstream immunohistochemical analysis.

## Abstract

骨髓活检是血液病理诊断的重要手段之一，对于多种良、恶性淋巴造血系统疾病均具有决定性的诊断意义，其诊断价值包括形态学观察，以及免疫组化、遗传学和分子生物学等辅助检测。由于骨髓活检组织本身的特殊性，脱钙是前期处理过程中必不可少的环节，其目的是将骨组织中钙盐去掉，保留完整的胶原纤维成分，以利于组织切片以及避免染色时掉片。如果骨髓活检脱钙不充分，则难以制片，但如果脱钙过度，又会严重破坏组织抗原活性，因此，一种脱钙效率高且抗原破坏小的脱钙方法对于临床病理骨髓活检十分重要。本文介绍一种高效且抗原破坏较小的骨髓活检组织脱钙方法：12％甲酸−8％盐酸脱钙液室温摇床脱钙，供广大同仁参考和指正。
