The sequence of the target DNA itself can affect PCR efficiency. The GC-rich sequences in target DNA may form secondary structures in the single strands produced by denaturation; this could reduce PCR efficiency.

Many insect pest species also transmit viruses. The sapsucking species are effective virus vectors, delivering virus particles directly into the vascular tissue, thereby permitting their rapid dissemination throughout the plant

The normal total circulating blood volume is about 8% of the body weight (5600 mL in a 70-kg man).  About 55% of this volume is plasma (3500 mL in a 70-kg man).

Most capillary walls are relatively impermeable to the proteins in plasma, and the proteins exert an osmotic force of about 25 mm Hg across the capillary wall (oncotic pressure) that pulls water into the blood.
