Actinic keratoses that develop on the lips are referred to as actinic cheilitis. The clinical appearance of an actinic keratosis is that of a small (several millimeters), red scaly papule or plaque, with induration and thickening of the epidermis.
1 Location: Ideally, the probe should be in close proximity to the forward or reverse primer, but should not overlap with a primer-binding site on the same strand. 2  Probes can be designed to bind to either strand of the target. 3  Melting temperature (Tm): Preferably, probes should have a Tm 6â8Â°C higher than the primers.
A reaction is considered reversible, if the reaction mixture contains the reactants as well as the products and if both the forward and the backward reactions are taking place under the experimental conditions. Reversible reactions are represented by a pair of half headed arrows . CaCO3 (s) CaO (s) + CO2 (g)
