Elongation

Elongation

(Science: radiobiology) parameter indicating the degree to which the cross-section of a toroidal plasma is non-circular. Kappa=b/a, where b and a are the vertical and horizontal minor radii. As kappa is increased, the confinement in relation to the total current improves, but the plasma also becomes more and more unstable to vertical displacements. A circular plasma has kappa of 1, a common value for elongated plasmas is 1.7, and the absolute limit is probably around 2.

Annealing Temparature

... anneal the first cycle at 50°C and the rest at 65°C. Denaturation for 10s will be enough, but a bit higher temperature 95-98°C might be better. Elongation depends on polymerase, so 1 min can be enough for Phusion, but 4 min will be required for Pfu.

Beetle identification

... the body? The one I saw had a long thin proboscis like a hoverfly that was longer than the body. The norm for this type of beetle is a short thin elongation with feathered antennae on the end, which I can see on your photo. One feature of this type of beetle is that they can cling with remarkable ...

RT-PCR

... varients,... with 4 different primers... Are you sure that your 2kb fragments is within the cDNA that you created? Did you try to increase the elongation time? Did you try different annealing temperatures?

Re: Camouflage in nature

... if they all independently increased the likelihood of survival? A slight greenishness would be an adaptation to avoid predation by birds. A slight elongation of the body would be an adaptation to avoid predation by birds. A line along the midline of the abdomen would be an adaptation to avoid predation ...
