Composition of BCS target-foundation complex
(A) A target-foundation complex assembled on the NGS chip.
(B) Magnification of the ligation site between binder tail and foundation. The left-sided DNA strand depicts the 5′ end of the nanobody binder tail (green and yellow) with 5′ phosphorylation (pink circle) and 3′ end of the foundation (orange). The right-sided DNA strand (blue) depicts the universal bridge sequence.
