a Nano-800 (Shanghai JP Analytical Instrument Co., Ltd.) spectrophotometer and stored at ?80 °C.
we also used the Nano-800 spectrophotometer to evaluate the products at each stage. The absorbance ratio between 260 and 280 nm (A260/A280) serves as a critical metric for assessing the purity of DNA or antibodies. Following the conjugation with SCN-DTPA and the DBCO-Mal linker, the A260/A280 ratio of (Ln3+)n-DNA exhibited significant shifts (Figure 1B), confirming effective conjugation of the components to (amino)n-DNA. Finally,
