Description

Description:

·         Antigen used: combination of selected parts of the specific antigens of Bordetella (B. pertussis - pertussis toxin (PT), filamentous hemagglutinin (FHA), adenylate cyclase toxin (ACT), tracheal colonization factor (TCF), B. parapertussis – outer membrane protein (Pertactin), adhesion (FimN), entericidin A (EntA).

·         Recombinant antigens are transferred to the nitrocellulose membrane (i.e. to the respective BLOT‑LINE (BL) strips).

·         If specific antibodies are present in the sample, they will bind to the respective antigens.

·         The complex is labelled with Conjugate and detected through a colour reaction with substrate (BCIP/NBT).

·         The kit enables 20 tests.

·         Short incubation periods, total assay time: approximately 1.5 h.

·         High sensitivity and specificity.

·         All reagents supplied are ready to use.

·         The kit may be used sequentially for smaller batches of samples (reagents are provided in sufficient quantities).

·         Positive and Negative controls included enabling validation of the tests.

·         BL strips equipped with conjugate control band and a control band indicating kits functionality and sensitivity.

·         Colour identification in compliance with antibody classes.

·         Identical (i.e. interchangeable) reagents (except for Conjugate) in all BLOT-LINE kits.

·         Evaluation of results – the intensity of the bands can be evaluated visually or by means of software (Immunoblot Software).

Applications:

·         Laboratory test for the detection of B. pertusis and B. parapertussis, confirmatory test to ELISA.

·         Laboratory test for the detection of B. pertusis and B. parapertussis.

Brief assay procedure:

1.       Dilute serum/plasma samples (1:51).

2.       Pipette diluted samples and controls into the channels of the tray and insert the BL strips.

3.       Incubate for 30 min at room temperature using a shaking apparatus.

4.       Wash 3 times for 5 min.

5.       Add Conjugate.

6.       Incubate for 30 min at room temperature using a shaking apparatus.

7.       Wash 3 times for 5 min.

8.       Add substrate (BCIP/NBT).

9.       Incubate for 15 min at room temperature using a shaking apparatus.

10.   Wash 2 times for 5 min in distilled water.

11.   Dry the strips and evaluate results using the validation strip enclosed or using Immunoblot Software.
