Specific detection of Cronobacter sakazakii in powdered infant formula using ssDNA aptamer (vol 146, pg 3534, 2021)

Abstract

The authors regret that there were errors in the buffer compositions described in section 2.3 of the article. On page 3535, the sentence beginning “Briefly, the DNA library pool…” should be correctly given as “Briefly, the DNA library pool was denatured in binding buffer (25 mM of glucose, 5 mM of MgCl2, 1 mg mL-1 of BSA, and 0.1 mg mL-1 of tRNA in preautoclaved 1X phosphate-buffered saline (PBS)) at 95 °C for 5 min and immediately chilled in an ice-bath before allowing the binding reaction with the target bacteria.” The sentence beginning “After a final partioning step…” should be correctly given as “After a final partioning step, bound ssDNA was eluted from the target bacteria by incubating the sample with 500 ？L of elution buffer (25 mM of glucose, 5 mM of MgCl2, and 1 mg mL-1 of BSA in pre-autoclaved 1X PBS buffer) at 95 °C for 10 min.” The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers. ？ The Royal Society of Chemistry.
