Compound Annual Growth Rate (CAGR) The compound annual growth rate (CAGR) is a useful measure of growth over multiple time periods. It can be thought of as the growth rate that gets you from the initial investment value to the ending investment value if you assume that the investment has been compounding over the time period.
In an ELISPOT assay, the membrane surfaces in a 96-well PVDF-membrane microtiter plate are coated with capture antibody that binds a specific epitope of the cytokine being assayed.ypically 200,000 - 400,000 PBMC will be used per well for an assay, but up to one million cells are commonly used for detection of rare events. ELISPOT is capable of detecting a single antigen positive cell within this population, giving it a theoretical low limit of detection of one in one million cells.
An excitatory postsynaptic potential (EPSP) is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell. A postsynaptic potential is defined as excitatory if it makes it easier for the neuron to fire an action potential. They are the opposite of inhibitory postsynaptic potentials (IPSPs), which usually result from the flow of negative ions into the cell. An Inhibitory Postsynaptic Potential (commonly abbreviated as IPSP) is the change in membrane voltage of a postsynaptic neuron which results from synaptic activation of inhibitory neurotransmitter receptors.
