Microfluidic Western blotting.
Rapid, quantitative Western blotting is a long-sought bioanalytical goal in the life sciences. To this end, we describe a Western blotting assay conducted in a single glass microchannel under purely electronic control. The μWestern blot is comprised of multiple steps: sample enrichment, protein sizing, protein immobilization (blotting), and in situ antibody probing. To validate the microfluidic...
متن کاملReagent pencils: a new technique for solvent-free deposition of reagents onto paper-based microfluidic devices.
Custom-made pencils containing reagents dispersed in a solid matrix were developed to enable rapid and solvent-free deposition of reagents onto membrane-based fluidic devices. The technique is as simple as drawing with the reagent pencils on a device. When aqueous samples are added to the device, the reagents dissolve from the pencil matrix and become available to react with analytes in the sam...
متن کاملMicrofluidic Western Blotting of Low-Molecular-Mass Proteins
We describe a microfluidic Western blot assay (μWestern) using a Tris tricine discontinuous buffer system suitable for analyses of a wide molecular mass range (6.5-116 kDa). The Tris tricine μWestern is completed in an enclosed, straight glass microfluidic channel housing a photopatterned polyacrylamide gel that incorporates a photoactive benzophenone methacrylamide monomer. Upon brief ultravio...

Histological Analysis and Immunohistochemistry Renal sections (3 μm thick) were stained with periodic acid-Schiff (PAS) and examined under light microscopy. Glomerulosclerosis index was semiquantitatively graded as 0 to 4+; vascular injury score as 0 to 3+; and tubulointerstitial injury score as 0 to 5+, according to the criteria reported previously. Ultrastructure of glomerular podocytes was a...
متن کاملImmunoprecipitation and western blotting
SKG or BALB/c T cells (3.0 £ 10) were stimulated for 72 h with plate-bound anti-CD3 mAb (2C11) in the presence or absence of plate-bound anti-CD28 mAb in RPMI-1640 medium supplemented with 10% fetal calf serum and 50 mM 2-mercaptoethanol. Cells were also stimulated with TPA (1.4 ng ml) and ionomycin (0.14 mM). KJ1.26þ T cells from DO or DO.SKG mice were stimulated with ovalbumin (323–339) pepti...
