A single step protein assay that is both detergent and reducer compatible: The cydex blue assay [PDF]

open access: yesELECTROPHORESIS, Wiley-VCH Verlag, 2016, 37 (20), pp.2595-2601, 2016
Determination of protein concentration in often an absolute pre-requisite in preparing samples for biochemical and proteomic analyses. However, current protein assay methods are not compatible with both reducers and detergents, which are however present simultaneously in most denaturing extraction buffers used in proteomics and electrophoresis, and in ...

Enzyme-Linked Immunosorbent Assays for Cholera Serology [PDF]

open access: yesInfection and Immunity, 1973
The enzyme-linked immunosorbent assay (ELISA) principle of Engvall and Perlmann, which employs antigen-coated tubes and enzyme-labeled anti-immunoglobulins, was elaborated for use in cholera serology. Immunoglobulin class-specific determinations of primary binding titers of antibodies to cholera exotoxin and endotoxin were more sensitive than were ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

open access: yesAdvanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Enzyme-linked immunosorbent assay for chlamydial antibodies [PDF]

open access: yesJournal of Clinical Microbiology, 1977
An enzyme-linked immunosorbent assay (ELISA) detected chlamydial antibodies in human sera. The assay antigen produced in cell cultures infected with Chlamydia psittaci was Formalin-fixed to microplates. Single convalescent-phase sera positive for chlamydial antibodies by a complement-fixation test were positive at even higher dilutions by ELISA. Paired

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...
