Antibody-drug conjugates (ADCs) represent a rapidly developing field within pharmaceutical biotechnology. ADCs are complex molecules composed of an antibody linked to a biologically active cytotoxic or radioactive compound. They combine the specificity of antibodies, which enables specific target cell binding, and the cell-killing activity of cytotoxic drugs, providing a method of delivering ...
siRNA, with a molecular weight of about 13 kDa, recruits the RNA-induced silencing complex (RISC) to mRNA through base pairing, thereby inhibiting protein translation. The mRNA is targeted for cleavage through the catalysis of the RISC protein Ago2, a member of the Argonaute family. In addition, other Ago proteins (Ago1, Ago3, and Ago4) catalyze endonuclease-mediated degradation of non-specific ...
Polyethylene glycol (PEG), a compound composed of repeated ethylene glycol units [-(CH2CH2O)n], is also known as Macrogols. PEG and PEG derivatives have the characteristics of non-irritation, good water solubility, good compatibility, etc. . At the same time, they possess excellent lubricity, moisture retention and dispersibility so that they can be used as adhesives, antistatic agents and ...
