Abstract: A well tracking device includes a rectangular frame including four sidewalls. The sidewalls define sets of opposing grooves, and the well tracking device is configured to receive or fit on top of a multi-well plate. The well tracking device also includes a well coordinate indicator positioned on an upper portion of the rectangular frame, that includes labels associated with columns and/or rows of the multi-well plate. The well tracking device also includes at least one slider that is configured to interface with a set of opposing grooves and slide along a width or length of the rectangular frame. The slider includes a plurality of openings disposed along the elongated shape of the slider.

Abstract: The invention relates to materials and methods for detecting interactions between lipid complexes and lipid binding agents. More specifically, the invention provides materials and methods for displaying lipid complexes, particularly those containing two or more different lipid molecules, on a hydrophobic surface so as to mimic their in vivo environment more closely than in other analytical methods. This allows more accurate detection of lipid complexes and even identification of lipid complexes which are not detected by other methods. The invention lends itself particularly well to array or microarray formats.
