The workflow is enabled by prepopulating nanowells with DMSO, which serves as a sacrificial capture liquid for microdissected tissues. The DMSO droplets efficiently collect laser-pressure catapulted LCM tissues as small as 20 μm in diameter with success rates >87%. Tissue treatment with DMSO can significantly improve proteome coverage, likely due to its ability to dissolve lipids from tissue and enhance protein extraction efficiency. The LCM-nanoPOTS platform was able to identify 180, 695, and 1827 protein groups on average from 12-μm-thick rat brain cortex tissue sections having diameters of 50, 100, and 200 μm, respectively.","ResourceType":"DeviceEquipmentTechnology","ParentResourceType":"Technology","DefiningManuscriptId":"PMID29941660","Publications":[],"Contributors":[{"Role":{"CanonicalId":"hirn-cv-ResourceRole-producer","Url":"resources.hirnetwork.org/api/v1/CV/","Name":"Producer","OntologyId":"HIRN"},"HirnUserId":"wei-jun_qian@hirnetwork.org","FirstName":"Wei-Jun","LastName":"Qian","EmailAddress":"weijun.qian@pnnl.gov","Organization":"Pacific Northwest National Laboratory","Consortia":["CBDS","OPP"]}],"Vendor":{"id":null,"Name":null,"Url":null},"VendorResourceName":null,"VendorResourceUrl":null,"VendorCatNumber":null,"VendorLotNumber":null,"DateCreated":"2019-04-26T01:22:20.0718639+00:00","DateModified":"2022-07-01T03:35:24.6195778+00:00","VersionId":"1","ModelVersion":"4.0","TechnologyData":{"Dependencies":[],"AssayTechnologyData":{"BioSampleType":[],"CellsTestedWith":[],"AssayTarget":{"CanonicalId":null,"Url":null,"Name":null,"OntologyId":null},"AssayCategory":{"CanonicalId":null,"Url":null,"Name":null,"OntologyId":null},"TechnologyType":{"CanonicalId":null,"Url":null,"Name":null,"OntologyId":null},"TechnologyPlatform":null,"CompatibleTools":[]},"DeviceEquipmentTechnologyData":{"CompatibleTools":[],"CellsTestedWith":[],"Placeholder":"Test"},"ServiceTechnologyData":{"CellsTestedWith":[],"Placeholder":"test"},"CodePipelineTechnologyData":{"Placeholder":"Test"}}}
