Abstract: Disclosed herein are methods for immobilizing membrane proteins or membrane protein complexes on analytical surfaces, which in some aspects comprise: obtaining a membrane protein or membrane protein complex comprising a capture moiety; immobilizing the membrane protein or membrane protein complex on the analytical surface by means of the capture moiety; and stabilizing at least one of the secondary, tertiary, or quaternary structures of the immobilized membrane protein or membrane protein complex by crosslinking with a crosslinking reagent. Also disclosed are analytical surfaces, which in some aspects comprise: a membrane protein or membrane protein complex comprising a capture moiety, wherein the membrane protein or membrane protein complex is immobilized on the analytical surface by means of the capture moiety, and wherein at least one of the secondary, tertiary, or quaternary structures of the membrane protein or membrane protein complex is stabilized by crosslinking.

Abstract: This invention relates to an ink jet ink composition comprising an aqueous medium and microgel particles, said particles comprising a crosslinked copolymer prepared from a monomer mixture comprising at least a crosslinking monomer, a polymerizable carboxylic acid monomer, and one or more polymerizable water insoluble vinyl type monomers. The ink composition may be a colorless ink or it may contain a colorant.

Abstract: An inkjet recording element having a porous support having thereon a fusible, porous ink-receptive layer of fusible polymeric particles. The invention is also directed to an inkjet printing process wherein the ink-receptive layer and/or the support in combination is capable of receiving substantially all of the ink-carrier liquid received by the inkjet recording element.

Abstract: A method of determining and applying a protective ink amount to be printed in addition to a plurality of colored ink amounts to make colored pixels in an image including determining the protective ink amount such that the sum of the protective ink amount and the colored ink amounts is greater than or equal to a minimum ink amount necessary to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.

Abstract: An apparatus and method of treating a recording element are provided. The apparatus includes a carrier removal station adapted to remove a predetermined percentage of carrier present in the recording element. A converting station is positioned downstream from the carrier removal station and is adapted to increase a durability characteristic of the recording element. A controller is electrically connected to at least one of the carrier removal station and the converting station so that an operating parameter of at least one of the carrier removal station and the converting station is individually adjustable.

Abstract: An inkjet recording element comprising a porous ink-receiving layer having interconnecting voids is disclosed in which an upper surface of the ink-receiving layer has been subjected to plasma treatment, and wherein the upper surface of the ink-receiving layer, prior to the plasma treatment, has a measured carbon elemental content of at least 40 percent. The invention can provide increased dot spread.

Abstract: A recording element printing and treating system and method are provided. The system includes a printhead for dispensing a liquid comprising a carrier onto a recording element. A carrier removal station positioned downstream from the printhead removes a predetermined percentage of carrier present in the recording element. A converting station positioned downstream from the carrier removal station increases a durability characteristic of the recording element. In one embodiment, printing, carrier removal, and converting are accomplished in a single unit. In an alternative embodiment, printing is accomplished in a stand alone unit while carrier removal and converting are accomplished in a second stand alone unit. In this alternative embodiment, transfer of the recording element can be accomplished automatically using a mechanical device or manually by a system user.

Abstract: An ink jet printing method, having the steps of: A) providing an ink jet printer that is responsive to digital data signals, B) loading the printer with ink-receptive elements having a support having thereon a continuous, coextensive porous ink-receptive layer, C) loading the printer with an ink jet ink composition comprising an aqueous-dispersible polyester having contained therein a water-insoluble dye, and D) printing on the ink-receptive element using the ink jet ink in response to the digital data signals.
