Small Interfering RNA (siRNA)

Moving the elements of life

siRNA Manufacturing

What is siRNA?

Small interfering RNA (siRNA) is a class of double-stranded RNA molecules, typically 20-25 base pairs in length, that is the key component of the RNA interference (RNAi) process. siRNA molecules are designed to target and degrade specific mRNA molecules, effectively silencing the expression of certain genes. This mechanism is used to treat diseases caused by the overexpression of harmful genes, including certain genetic diseases and viral infections​.

How siRNA works

siRNA functions by binding to its target mRNA within the RNA-induced silencing complex (RISC). Once bound, the RISC complex degrades the mRNA, preventing it from being translated into protein. This process offers a highly specific method of gene silencing, allowing for the precise targeting of disease-causing genes​​.

Key applications

  1. Gene Silencing: Reducing the expression of genes involved in diseases.
  2. Antiviral Therapies: Targeting viral RNA to reduce infection severity.
