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 phosphor plate at the bottom of the tube converts these electrons into photons (Richmond 2005). Continuing on their path, the group of photons strikes a normal CCD which forms an image. In this process, these cameras use the photoelectric effect and its reverse operation as well (Richmond 2005).
