Abstract: This disclosure relates to inexpensive and efficient methods of preparing egg white (e.g., obtained from eggs laid by transgenic chickens) for bulk chromatographic isolation of proteins (e.g., recombinant proteins) from the egg white, as well as method of filtering acidified egg white and methods of isolating proteins from the egg white.

Abstract: In an embodiment, a system includes a frame configured to support a load, a first set of wheels provided on the frame, a second set of wheels provided on the frame, and a controller. The first set of wheels is configured to descend or ascend in response to the controller, and is oriented to move in a first direction. The second set of wheels is configured to descent or ascend in response to the controller, and is oriented to move in a different direction from the first direction. The controller configured to control the descent and ascent of the second set of wheels and the first set of wheels.

Abstract: The present invention is related a method of purifying a heterologous protein from an egg white. In some embodiments, the disclosure is directed to a method of purifying a heterologous protein from an egg white comprising the heterologous protein, the method comprising, (a) adjusting the pH of the egg white to a pH of 5.8 to 6.5 to form a pH-adjusted egg white; (b) filtering the pH-adjusted egg white of (a) and collecting a first filtrate; (c) subjecting the first filtrate of (b) to a hydrophobic interaction chromatography matrix, and collecting a first eluate comprising the heterologous protein; (d) adjusting the pH of the first eluate of (c) to a pH of 5.0 to 5.6 to form a pH-adjusted eluate; (e) filtering the pH-adjusted eluate to obtain a second filtrate; (f) adjusting the pH of the second filtrate to a pH of 3.0 to 4.0 to form a pH-adjusted second filtrate; (g) neutralizing the pH-adjusted second filtrate of (f) to a pH of 5.0 to 8.

Abstract: The present invention is a flow distributor and integral bed support for a chromatography column. The flow distributor has an outlet extending through it and a bottom face across which is secured a bed support. The bottom face has a series of ribs extending radially outward from a center portion of the face. The bed support is secured to the flow distributor about its outer periphery and this amount of available surface area of the flow distributor and/or face that is used to secure the bed support is less than about 10%. A distribution disk is arranged over the inlet and extends across from about 1 to about 30% of the flow distributor's surface area, ending just short of the inner edge of the ribs closest to the center point of the flow distributor face. This disk is mounted on two or more legs so as to be of substantially the same height as the ribs. The disk projects the fluid flow in a 360° radial distribution without any noticeable partitioning.
