Volta potential by its work function, and so dissimilar metals can show an electric potential difference even at equilibrium. The Volta potential is "not" an intrinsic property of the two bulk metals under consideration, but rather is determined by work function differences between the metals' surfaces. Just like the work function, the Volta potential depends sensitively on surface state, contamination, and so on. The potential is given by the formula: formula_1, where V is the potential, The Volta potential can be significant (of order 1 volt) but it cannot be measured directly by an ordinary voltmeter. A voltmeter does not measure vacuum
Thymidine kinase 1 of malignancy, furthermore, TK-1 has been found to be elevated in serum even before clinical symptoms appear. This offers the potential for earlier therapy. Elevations in serum TK-1 have been found to correlate with the return of breast and other forms of cancer TK-1 can be used to detect cancer earlier, determine what stage it is in, and detect recurrence. Thymidine Kinase 1 can be measured based on its enzyme activity or using immunoassay. Thymidine kinase 1 Thymidine kinase 1, soluble (gene name TK1), is a human thymidine kinase. Two forms of this protein have been identified in animal cells,
