WebMar 9, 2024 · As shown in Supplementary Fig. S2, the chemical shifts at δ 3.44 (ppm) confirm the successful conjugation of the NH2-PEG-biotin and OPBA (red arrows), and the chemical shifts around δ 3.70 (ppm) represent the 4H in PEG (green arrows). WebIn science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction.Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.Commonly used are parts-per-million (ppm, 10 −6), …
