چکیده

We describe buffer for both immunoelectrophoresis and zone electrophoresis procedures in agarose gels, Tricine [N-tris(hydroxymethyl)methylglycine] and Tris [2-amino-2-(hydroxymethyl)-1,3-propanediol] being the main components. This buffer eliminates the procurement cost and inventory control associated with formulation of barbital buffers. We compare it with other common buffer formulations.

Hemoglobin electrophoresis at alkaline pH on agarose gels.

We describe a modified thin agarose-gel system for use in primary hemoglobin screening by electrophoresis. The system makes use of a Tris-EDTA-borate-buffered agarose gel (pH 8.8) and a sodium barbital electrophoresis buffer (pH 8.6). Separation is effected in 20 min at a constant potential of 250 V. Eight samples can be simultaneously separated and the patterns made visible in 47 min. There ar...

Resolving Transferrin Isoforms via Agarose Gel Electrophoresis.

OBJECTIVE Cerebrospinal fluid (CSF) leaks may present as rhinorrhea or otorrhea and can lead to life-threatening complications if not detected. The usefulness of the morpholinopropanesulfonic acid (MOPS)-histidine buffer in detecting β₂-transferrin, which is only found in the cerebrospinal fluid, was compared with the standard barbital buffer. METHODS We evaluated 20 aural or nasal patient sp...

Enhanced detection of Australia antigen in serum hepatitis patients by discontinuous counter-immunoelectrophoresis.

The use of discontinuous counter-immunoelectrophoresis enhanced the reaction between Au/SH antigen and its antibody in agarose. The ionic strength of the Veronal buffer used in the agarose was 0.015 mu, whereas 0.075 mu Veronal (both pH 8.6) was used for anode and cathode buffers. Electroendosmosis is increased under such conditions. Au/SH antigen and antibody reacted to give sharp lines within...

Isolation and Characterization of Human Factor VIII

Factor VIII (antihemophilic factor) has been purified approximately 500.fold from the cryoprecipitate fraction of human plasma. The isolation procedure involves adsorption of contaminants with Al(OH),, column chromatography on tricalcium citrate-cellulose, precipitation with concanavalin A, and an agarose gel filtration step. The linal product is homogeneous when examined by zone electrophoresi...

Purification of membrane proteins from Acholeplasma laidlawii by agarose suspension electrophoresis in Tween 20 and polyacrylamide and dextran gel electrophoresis in detergent-free media.

Four of the membrane proteins from Acholeplasma laidlawii that are soluble in the nonionic detergent Tween 20 have been purified by preparative electrophoretic techniques utilizing different supporting media. The last purification step for two of the major proteins was a preparative polyacrylamide gel electrophoresis performed in the absence of any detergent. The proteins were recovered by cont...
