Protur™ B.J. kit for Beckman Coulter Paragon® Electrophoresis - GB: Instructions for use


1. General

Date: 4 sep-03 - Revision: 01
EURO PN 844111005
PN 10-004080
20 tests per kit

figure 1

2. Intended use

The kit is intended for the immunofixation of proteins and Bence Jones proteins in non concentrated urine.

3. Principle of the test

Proteins in an electric field migrate toward one of the electrode poles at varying rates. Migration separates the proteins. When specific antisera combine with specific proteins, antigen-antibody precipitation will occur.

The Protur B.J.™ kit contains components for the electrophoretic separation of proteins in non concentrated urine in a buffered agarose gel.

After electrophoresis, antiserum is applied.

7. Training

The operator should be familiar with Beckman Coulter's Paragon Electrophoresis System.

8. Reagent preparation and storage

Agarose Gels: Just prior to use, carefully remove a Gel from the foil package. Gels should be stored at room temperature, 8°C to 30°C, until expiration date. Improper temperature or storage conditions can result in atypical migrations. DO NOT STORE GELS NEAR HEAT EMITTING DEVICES. For example: CRT, computer, or table top instrument. DO NOT REFRIGERATE OR FREEZE.

Protur Plus™ Equilibration Buffer: READY FOR USE.

Protur Plus™ Electrophoresis Buffer Mix 200mL of buffer with 800mL of deionised water.

Buffer is stable in closed container for 60 days.

Protus Plus™ Staining Solution:

  • prepare acid-alcohol solution: 500 mL deionised water, 300 mL methanol, 200 mL acetic acid.
  • mix 100 mL Dye with 200 mL acid-alcohol solution.

Saline solution:

8.5 g NaCl in 1 L deionised water.

Store reagents at room temperature

9. Type of specimen

Use fresh unconcentrated urine.

10. Instrument preparation

See Paragon® Electrophoresis System.

Place in wet processor:

  • container 1: dye solution

  • container 2: deionised water
