应用
该制剂可用作核酸（DNA或RNA）沉淀的载体。作为惰性材料，它可以代替tRNA或超声处理的DNA。
20 μg糖原（1 μl溶液）可以从1 ml的体积中沉淀出pg量的DNA或RNA。
在一个典型实验中，将5 pg [3H]标记的小牛胸腺DNA溶解于含1 mM EDTA、0.4 M LiCl的500 μl 10 mM Tris-HCl（pH 8.0）中。加入1 μl糖原溶液（20 μg糖原）作为载体，然后在-15至-25 °C下用1.2 ml乙醇沉淀，并在-15至-25 °C下保存3小时。 离心（12 000×g 10分钟）后，总放射性存在于沉淀物中。不添加糖原，DNA不会沉淀。

Deep sequencing of RNAs has greatly aided the study of the transcriptome, enabling comprehensive gene expression profiling and the identification of novel transcripts. While messenger RNAs (mRNAs) are of the greatest interest in gene expression studies as they encode for

Progerin accumulation disrupts nuclear lamina integrity and causes nuclear structure abnormalities, leading to premature aging, that is, Hutchinson-Gilford progeria syndrome (HGPS). The roles of nuclear subcompartments, such as PML nuclear bodies (PML NBs), in HGPS pathogenesis, are unclear. Here, we

In vitro transcription of DNA with phage RNA polymerases is currently the most efficient method to produce long sequence-specific RNA. While the reaction can yield large quantities of RNA, it contains impurities due to various unwanted activities of the polymerases.
