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.
Forward primer is the primer located at the 5'-end of the gene, and reverse primer is that at the 3'-end.I normally call them as sense and antisense primers. This makes more sense. The sense primer has the same sequence as the sense strand (that produces the mRNA).The antisense primer has the complimentary sequence.y relaxin Â» Apr 25 2006 5:14 pm.
