Glucatel Glucatel Kit
(1->3)--D-glucan Detection
Product Insert | Product Info Sheet

Product Description

The Glucatell assay kit is specific for (1->3)--D-glucan. The assay is based upon a modification of the Limulus Amebocyte Lysate (LAL) pathway. The Glucatell reagent is processed to eliminate Factor C, and is therefore specific for (1->3)--D-glucan. The reagent does not react to other polysaccharides, including beta-glucans with different glycosidic linkages.

Sample to Lysate Ratio

Kinetic assay: 25 L of sample or standard is mixed with 100 L of reagent in a microplate.

End-point assay: 50 L of sample is mixed with 50 L of reagent in a microplate.

Test Performance

Kinetic assay: The Glucatell/sample mixture is incubated at 37C 1C in a microplate reader equipped with a 405 nm filter and analyzed over time by a suitable software program.

End-point assay: The Glucatell/sample mixture is placed in a microplate heating block at 37C 1C for the recommended time period. 50 L each of the three diazo reagents are added to the mixture to stop the reaction, which is then read at 540-550 nm. Concentration of the samples is analyzed by a suitable software program.

Product Stability

Store all reagents at 2-8C in the dark. Reconstituted Glucatell reagent should be stored at 2-8C and used within 2 hours. Alternatively, reconstituted Glucatell reagent can be frozen at -20C for 20 days, thawed once and used. The diazo-reagents should be used the day they are prepared.

Product Packaging

The Glucatell kit is available as either an end-point or kinetic chromogenic assay for use in microplates. The kit contains the Glucatell reagent, a (1->3)--D-glucan standard, buffer, diazo reagents (end-point kit only), glucan-free water, and glucan-free microplates.
