When nature turns deadly: A look at Abrin
What is abrin? In certain parts of Asia and Australia, grows a flowering plant of the bean family Fabaceae, known as Abrus precatorius, also more commonly as jequirity bean or rosary pea [1]. It’s a delicate, perennial climber but extremely invasive and classified as a weed in several countries. However, what…
Specific peptide conjugation to a therapeutic antibody leads to enhanced therapeutic potency and thermal stability by reduced Fc dynamics
Peptide conjugation to trastuzumab A 23 amino acid peptide, acetyl-(Lys[Azide]) RRRGSGPDCAYHKGELVWCTFH-NH2, was chemically synthesized and modified with a succinimidyl glutarate linker at Lys14 (the numbering starts with Lys[Azide]) (Fig. 1A). To allow payload conjugation and increase the solubility of the conjugates, the N-terminus of the peptide was extended based on a…
