● 产品简介：
Betaine, DMSO and formamide helps in reducing the secondary
structure of GC rich templates and assists amplification of these templates.
Betaine is used at3.5Mto0.1M, DMSO should be used between 2-8%,
however 10% DMSO can reduce Taq polymerase activity by up to 50%. Formamide is
generally used at 1-5%. It has been our experience that the use of DMSO in
combination with betaine is superior to using formamide.
● 贮存：-20℃贮存。有效期二年。
● 使用说明：
1．-20℃保存的DMSO常温融化，混匀。
2. 根据根据PCR反应体系，加入适量体积的DMSO溶液。
