Extraction method and extraction kit for bone marrow cell genome DNA

The invention provides an extraction method and an extraction kit for a bone marrow cell genome DNA. The extraction method comprises the following steps: adopting proteinase K and lysate to process abone marrow cell sample, then adopting ribonuclease digestion, mixing with absolute ethyl alcohol, then putting the mixture into a silica gel adsorption column for adsorption, and then adopting a first scrubbing solution, a second scrubbing solution and an eluant in sequence for treatment to obtain the purified bone marrow cell genome DNA. According to the extraction method of the bone marrow cellgenome DNA provided by the invention, by controlling the formula and adjusting the pH value and ion concentration, the gDNA with high quality and high purity can be extracted under the condition of low cost, and the extraction effect is stable and reliable. 本发明提供了种骨髓细胞基因组DNA的提取方法和提取试剂盒，提取方法包括：采用蛋白酶K和裂解液处理骨髓细胞样品，然后采用核糖核酸酶消化，与无水乙醇混合后放入硅胶吸附柱中吸附，依次采用第洗涤液、第二洗涤液和洗脱液处理，得到纯化后的骨髓细胞基因组DNA。本发明的骨髓细胞基因组DNA的提取方法通过控制配方、调节pH值和离子浓度等，能够在低成
