  Enriching Low-Abundance Serum & Plasma Proteins   AWARD: $30,000 USD | DEADLINE: 10/01/11 | ACTIVE SOLVERS: 254 | POSTED: 8/01/11   Source: InnoCentive Challenge ID: 9932714 Type: Theoretical-licensing   Detailed Description & Requirements   Concentrations of proteins in serum and plasma span up to 10 orders of magnitude – e.g. from serum albumin (50 mg/ml) to some cytokines and chemokines (<5 pg/ml)   Protein molecules most useful to researchers exist at levels that are approximately at or below the 10,000 pg/ml range. Detection and quantification of these low-abundance proteins is obscured by the presence of high abundance proteins. Current methods for reducing the concentration of high-abundance proteins are either inefficient, targeted at certain proteins, or introduce bias and other artifacts.   The Seeker is looking to identify novel methods to reliably reduce or eliminate high abundance proteins so that detection of protein analytes present at the 1-10 ng/ml scale or lower may be accurately detected.   The Seeker envisages that a sample preparation techniques may be the most likely route to a solution. However, alternative approaches are also welcomed. The Seeker is highly experienced in sample preparation technologies for reduction of high-abundance proteins & is not interested in simple proposals of commercially available, or published, technologies and techniques.   The Seeker is aware of the following ‘sample enrichment’ technologies for reducing the concentration of high abundance proteins from serum & plasma. The techniques are listed together with their limitations for the Seeker:   Immunoaffinity depletions– depletions are extremely specific to the antigens the antibodies target. Commercially available kits commonly deplete 6-20 high abundance proteins with more than 90% efficiency. Although this enables detection of more low-abundance proteins, the column-based process induces some bias in low-abundance protein   [更多]

厂方需要一种“强化干燥系统”,必须是一个改进的灭菌工艺,即通过优化干燥时间,从而减少整个过程时间。“强化干燥系统”的另一个重要目标是:无菌容器总是处在完全干燥的灭菌过程中,确保灭菌的可靠性和安全性。 具体如下:https://www.innocentive.com/ar/challenge/9933714 The Challenge is to come up with an “Enhanced Drying System” that will improve a sterilization process by optimizing the drying time and thus reducing the overall process time. Another important goal for the “Enhanced Drying System” is to ensure, that the sterile containers always get completely dry in the sterilization process and to increases the perceived reliability and safety of the sterilization process. This Challenge requires only a written proposal. Source: InnoCentive Challenge ID: 9933714 Challenge Overview Steam sterilized containers of instruments sometimes contain visible moisture upon opening even after an extended drying cycle. Although the liquid does not compromise the sterile barrier, its appearance causes doubts about sterilization and leads to repeat sterilizations costing time and money. The Challenge is to remove liquid moisture from the container during or after the sterilization process without extending the drying cycle time economically. This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. Solutions which are simple, practicable and have a low implementation cost are highly preferred. To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution.   [更多]
