-def: "A scale that measures an object's temperature over absolute zero, the theoretical coolest temperature where all molecular and atomic motion ceases. On the Kelvin scale, the freezing point of water is 273 (273 K = 0 o C = 32 o F)." [PMID:14755292]
+def: "The kelvin (K) is the SI unit of thermodynamic temperature. It is defined by taking the fixed numerical value of the Boltzmann constant k to be 1.380649×10-23 when expressed in the unit J·K-1, which is equal to kg·m2·s-2·K-1, where the kilogram, metre and second are defined in terms of h, c and caesium frequency. It is equivalent to -273.15°C / -459.67°F." [PMID:14755292]

+name: Split Intein-Mediated Protein Ligation
+def: "Bait protein is fused to a standard protein fusion tag and an intein fragment, prey a with a different protein fusion tag and the complementary intein fragment. The bait and prey are co-expressed in a cell line where the association of bait and prey brings the intein fragments into close proximity, allowing them to reconstitute a fully functional intein, which then catalyzes its own excision and the concurrent ligation of the bait and the prey peptides (as well as the standard protein fusion tags). The resulting spliced protein can be resolved by regular western blot analysis due to its altered mobility, while the presence of the standard protein fusion tags allows visualization or purification of protein using regular biochemical techniques."
