A tubal ligation involves cutting the fallopian tubes, which carry eggs from the ovaries to the uterus.
Tubal ligation prevents pregnancy in two ways: it prevents sperm from reaching an egg and it prevents eggs from reaching the uterus.
Some women choose to have tubal ligation done just after giving birth.
In particular we are developing an efficient ligation approach in which two peptide fragments are coupled while still attached to the solid-phase.
An innovative approach is developed for monitoring the activity of E. coli DNA ligase catalyzing nucleic acid ligation in the report.
