It is the fully automated agarose gel system made by Interlab. Microgel performs in full automation all electrophoretic phases of Serum Proteins, Lipoproteins, Alkaline and Acid Hemoglobins, CSF, Unconcentrated Urine Proteins and in semi automation Immunofixation and the Isoenzymes of LDH, CPK and Alkaline Phosphatase.

Until now it was unthinkable to have a truly walk away agarose gel system. Thanks to its unique features, Microgel has the capability to work in a continuous mode and an extremely high throughput can be achieved - up to 150 tests per hour

Protein Electrophoresis kit Serum Proteins and Concentrated Urines

The Microgel/Interlab G26 Serum Protein/Concentrated Urine Electrophoretic methods, provide a new level of total automation on agarose gel.

You simply pipette the specimens (pure or concentrated) into the sample wells, put the gels in the holders, start the instrument and walk away!

Human body fluids contain a varied mixture of proteins and protein complexes. Each of these protein entities apparently fulfills a specific function in physiological process; furthermore, it is well known that the levels of various proteins in blood serum bear a close relationship to states of health and disease. Of the many techniques available for separating proteins, electrophoresis is a well established and versatile technique, routinely used in clinical laboratories. The most popular method of electrophoretic protein analysis is “zone electrophoresis” on agarose gels. Serum Protein Electrophoresis (SPE) performed at pH 8.9 yields five bands: albumin and four globulins (each fraction containing a number of different proteins): alpha 1(

1), alpha 2 (

2), beta (

), and gamma (

). Evaluation of single bands by visual inspection provides valuable diagnostic support as it offers a display of the major proteins involved in functional and pathological processes.

The appearance of plasma proteins in the urine (proteinuria) is of great value in the evaluation of renal function. The physiological proteinuria is defined as approximately 150 mg of protein found in a 24 hour urine collection.
Electrophoresis of urine is the best way to detect abnormal proteins in urine.
The presence of an abnormal band requires complementary identification by Immunofixation (for example to assess the presence of a Bence-Jones protein) Abnormal proteins in urine can be present with a normal proteinuria.
