siRNA Design

Optimization of siRNA Design

The length of siRNA is 7-8 nm, the diameter is 2-3 nm, the molecular weight is 13-14 kDa, and it is hydrophilic. Therefore, unmodified and naked siRNA cannot passively cross […]

Nectin-4: A New Target of ADC

Overview of Nectin Nectin, a cell adhesion molecule belonging to the Immunoglobulin (Ig) superfamily, is a homologue of poliovirus receptor (PVR/CD155). It also known as poliovirus receptor-associated protein Receptor Related Protein (PVRL). […]

Peptide-drug Conjugate

Overview of Peptide-drug Conjugate

The concept of drug conjugates originated in the early 20th century. In 1910, Paul Ehrlich proposed the “Magic Bullet” theory, which aimed to describe the concept of a drug that […]
