From
Recombinant Antibody
Specificity
This antibody is specific for Mycobacterium avium. Mycobacterium avium together with Mycobacterium intracellulare causes the disease called Mycobacterium avium-intracellulare infection or Mycobacterium avium complex infection in humans.
Alternative Names
UniProt
Immunogen
This antibody was generated by panning a phage library generated from sheep were infected via the oral route with two doses of 109 CFU of a low-passage M. avium subsp. paratuberculosis strain W. against mycobacterial cell suspensions were harvested from culture.
Application Notes
The scFv version of this antibody was immunoblotted on M. avium subsp. paratuberculosis lysate. The result showed a positive reaction. Furthermore, flow cytometry on cobacterium sp. surface antigen was performed using this antibody, the antibody showed binding to M. avium subsp. avium cells. To determine whether surface-bound SurfS1.2 or SurfS2.2 could influence mycobacterial growth, M. avium subsp. avium was grown in Middlebrook broth, the antibody prevented clumping in M. avium subsp. avium cells. The antibody was also used to magnetically separate M. avium subsp. paratuberculosis from faecal samples (Berger et al, 2006; pmid:16960114).

Note on publication
The production of single-chain antibodies with defined specificity for M. avium subsp. paratuberculosis surface proteins was described. Single-chain antibodies (scFv) were generated from sheep with Johne's disease by cloning heavy-chain and lambda light-chain variable regions and expressing these in fusion with gene III of filamentous phages.
