Internal control: This is a control sequence that is amplified in the same reaction as the target sequence and detected with a different probe (i.e., duplex PCR is carried out). An internal control is often used to rule out failure of amplification in cases where the target sequence is not detected.
How it works. A symporter is an integral membrane protein that is involved in the transport of many differing types of molecules across the cell membrane. The symporter works in the plasma membrane and molecules are transported across the cell membrane at the same time, and is, therefore, a type of cotransporter. The transporter is called a symporter, because the molecules will travel in the same direction in relation to each other. This is in contrast to the antiport transporter. Typically, the ion will move
LogManager is used to keep record of all of the loggers. A logger is an object that wants to log some data. Appender is an object that writes log data to some data store, application or library. Filter is a condition that can be applied to an Appender to restrict the writing of log data. Layout is the display formatting that will be used for the log data when it is written to the Appender. Repository is the central store for the log4net configuration and LogManager.
