    Abstract: A method for producing AAV, without requiring cell lysis, is described. The method involves harvesting AAV from the supernatant. For AAV having capsids with a heparin binding site, the method involves modifying the AAV capsids and/or the culture conditions to ablate the binding between the AAV heparin binding site and the cells, thereby allowing the AAV to pass into the supernatant, i.e., media. Thus, the method of the invention provides supernatant containing high yields of AAV which have a higher degree of purity from cell membranes and intracellular materials, as compared to AAV produced using methods using a cell lysis step.

    Abstract: A dual purpose current mode logic (“CML”) latch circuit is provided which includes a CML latch operable to receive at least a pair of differential input data signals and at least one clock signal. The CML latch is operable to generate at least one output signal in accordance with the states of the pair of input differential data signals. A mode control device is operable to receive a mode control signal to operate the CML latch as a buffer or as a latch. In such way, when the mode control signal is inactive, the CML latch generates and latches the output signal at a timing determined by the at least one clock signal, and when the mode control signal is active the CML latch generates the output signal such that the output signal changes whenever the states of the pair of differential input data signals change.
