Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of life science technology, specifically is a SiRNA annealing device. BACKGROUND
[0002] SiRNA is a short RNA molecule that can inhibit the expression of specific genes by interfering with RNA. SiRNA annealing refers to the process of SiRNA molecules binding to target RNA. When SiRNA binds to target RNA, SiRNA will inhibit the translation and expression of target RNA through the mechanism of RNA-induced target RNA degradation. The principle of SiRNA annealing involves the complementary pairing of SiRNA and target RNA. SiRNA molecules are usually composed of two strands, the guide strand and the antisense strand. The guide strand is completely complementary to the sequence of the target RNA, while the antisense strand is complementary to the guide strand. When SiRNA binds to target RNA, the guide strand will complementarily pair with the sequence of the target RNA to form a double-stranded RNA complex. Oligonucleotide annealing is a common experimental technique widely used in biology, biochemistry, and genetics. It controls the temperature change of the primer to improve the affinity and pairing ability of the primer, so that it can specifically bind to the target sequence.
[0003] Based on the above, the present inventors found that there are the following problems: the current SiRNA annealing is roughly divided into three steps: heating to a set temperature, maintaining this temperature for a period of time, and reducing to room temperature. During the SiRNA annealing process, the temperature change needs to be precisely controlled. If the temperature is too high, the primer will not be stable in binding to the target RNA, and if the temperature is too low, the primer will bind to non-specific sequences.
[0004] Therefore, in view of the above, the existing structure and deficiencies are studied and improved, and a SiRNA annealing device is provided to achieve a more practical value. INVENTION CONTENTS
