Abstract: Methods, systems, and devices for sampling/isolating material from cells. An exemplary system may comprise a chip including an electrode array of sampling electrodes arranged along a surface of the chip. A cell-receiving area may be located adjacent the surface of the chip. The system also may comprise a tag array of tags supported by the chip and aligned with the electrode array. Each tag of the tag array may include an identifier that is unique to the tag within the tag array. Each tag may be configured to bind nucleic acids, or a capturing agent distinct from the tag may be aligned with each sampling electrode of the electrode array to capture a protein or other analyte of interest. The system further may comprise a control circuit configured to apply an individually controllable voltage to each sampling electrode of the electrode array and measure an electrical property of the sampling electrode.

Abstract: The present invention provides methods of detecting an antigen in a sample comprising contacting the sample with affinity agents to form an antigen-affinity agent-label complex, separating the antigen-affinity agent-label complex from uncomplexed components, partitioning label from the separated sample into multiple partitions, and detecting the presence of the label in one or more partitions. Compositions and kits for detecting an antigen in a sample are also provided.

Abstract: Sample holding system, including methods and apparatus, including a holder defining a well having a wicking promoter that encourages flow of a sample to the bottom of the well. Methods of making and using the holder are also disclosed.

Abstract: A burn protection system for a pipe having a central axis comprises a standoff disposed about the pipe. The standoff includes a frame and a plurality of circumferentially spaced pipe engagement members coupled to the frame. Each pipe engagement member is radially positioned between the frame and the pipe and engages the pipe at a single point of contact. In addition, the burn protection system comprises a cage mounted to the frame of the standoff.

Abstract: Fluorescence validation material comprising first layer and a second layer that is useful as validation and calibration standards as well as validation plates including one or more fluorescence validation materials. Moreover, this invention includes methods for using validation plates and fluorescence validation materials of this invention to validate and calibrate instruments.
