In clinical and scientific experiments, decalcification of bone samples is the first step in the detection of bone samples. How to effectively remove the calcium component in the bone and retain the biological substances in the tissue cells, including DNA, RNA and protein, is related to the success or failure of the subsequent molecular extraction and in situ detection of the sample.
Beijing finowaikang technology co., ltd. has introduced a special formula for RNA protection authorized by the United States. the rapid decalcification solution developed includes mixed proportioning acid, stabilizer and other auxiliary components. on the basis of rapid decalcification, DNA,RNA and protein in bone sample cells can be preserved to the greatest extent to ensure subsequent detection.

Mouse teeth were prepared into paraffin sections after 22 hours of rapid decalcification solution treatment, and RNAISH detection was carried out. The red signal point in the figure is the positive RNA signal detected.

Human bone marrow samples were treated with rapid decalcification solution and prepared into paraffin sections for H & E staining.

Human bone marrow samples were prepared into paraffin sections after rapid decalcification solution treatment, and RNA ISH detection was carried out. White, red and green signal points in the figure are three different positive RNA signals detected.

Human bone marrow samples were prepared into paraffin sections after rapid decalcification solution treatment, and mlF detection was carried out. The red, green, yellow and white signals in the figure were CD68, CD20, CD31 and CD11C immunofluorescence staining positive results respectively.
