| 20100182877 | ULTRASOUND-MEDIATED HIGH-SPEED BIOLOGICAL REACTION AND TISSUE PROCESSING - Methods of fixing and processing tissue and samples on a membrane by using ultrasound radiation as a part of the method are presented. Ultrasound of a frequency in the range of 0.1-50 MHz is used and the sample or tissue receives 0.1-200 W/cm | 07-22-2010 |
| 20100136613 | PRESSURE-ASSISTED MOLECULAR RECOVERY (PAMR) OF BIOMOLECULES, PRESSURE-ASSISTED ANTIGEN RETRIEVAL (PAAR), AND PRESSURE-ASSISTED TISSUE HISTOLOGY (PATH) - A method is disclosed for reversing fixation-induced cross-linking in tissue specimens that have been preserved for histological examination. The method involves placing the fixed tissue in a liquid under elevated temperature and pressure conditions that are sufficient to reverse the fixation-induced cross-linking, restore antigenicity to proteins, and permit improved molecular and proteomic analysis of the preserved tissue specimen. Methods are also disclosed for processing tissues for histological examination under elevated pressure conditions that enhance the perfusion of liquid reagents into the tissue and reduce overall processing times. | 06-03-2010 |
| 20100112577 | APPARATUS AND METHODS FOR EFFICIENT PROCESSING OF BIOLOGICAL SAMPLES ON SLIDES - Methods for treating biological samples on microscope slides are set forth. One aspect of the invention is the use of predried reagents in wells on trays onto which the slides are placed, especially the use of predried reagents which dissolve sequentially. Yet another aspect of the invention is the use of external controls placed directly on a microscope slide in conjunction with a biological sample to be assayed. The external controls can be conveniently placed on a membrane which can be affixed to the slide. A further aspect of the invention is a specially designed tray to allow whole chromosome painting of all chromosomes of a cell sample on a single slide. The invention is also drawn to a coverslip with concave wells which act as reaction chambers when placed against a slide and filled with buffer. Preferably a reagent is predried in the well. A further aspect of the invention is a method of reacting samples on slides by placing them into a reaction chamber together with a coverslip which has a predried reagent on it. | 05-06-2010 |
