Description générale

IgA antibody is secretory antibody and is present abundantly in mucous linings of gastrointestinal, respiratory and genitourinary tracts, tears and saliva. Thus secretory IgA contributes to the humoral defense mechanism against the pathogens on mucosal surfaces
IgA, κ from murine myeloma is produced by TEPC 15 tumor line that is pristane-induced plasmacytoma originated and carried intraperitoneally in BALB/c mice. The antibody is specific for κ chain of mouse IgA. The purified immunoglobulin preparation is non-reactive with anti-mouse IgM, IgG1, IgG2a, IgG2b, and IgG3.
The TEPC 15 tumor line that produces mouse IgA,k is pristane-induced plasmacytoma originated and carried intraperitoneally in BALB/c mice. Immunoglobulin G (IgG) belongs to the immunoglobulin family and is a widely expressed serum antibody. An immunoglobulin has two heavy chains and two light chains connected by a disulfide bond. It mainly helps in immune defense. It is a glycoprotein. IgG is a major class of immunoglobulin. Mouse consists of five immunoglobulin classes- IgM, IgG, IgA, IgD and IgE. IgA molecules in the serum are mostly dimeric. IgA is found in saliva, tracheobronchial secretions, genitourinary secretions, milk and colostrum.

Spécificité

Antigen Specificity: phosphoryl choline

Application

Anti-Mouse IgA, κ antibody was used as secondary antibody in ELISA and immunoflourescence.
IgA, Kappa from murine myeloma has been used in:
  • immunofluorescence assay
  • enzyme-linked immunosorbent assay (ELISA)
  • invasion assays
  • western blotting

Actions biochimiques/physiologiques

Immunoglobulin G (IgG) helps in opsonization, complement fixation and antibody dependent cell mediated cytotoxicity.

Bacteria growing within biofilms are protected from antibiotics and the immune system. Within these structures, horizontal transfer of genes encoding virulence factors, and promoting antibiotic resistance occurs, making biofilms an extremely important aspect of pneumococcal colonization and persistence. Identifying environmental

It is unclear whether Streptococcus pneumoniae in biofilms are virulent and contribute to development of invasive pneumococcal disease (IPD). Using electron microscopy we confirmed the development of mature pneumococcal biofilms in a continuous-flow-through line model and determined that biofilm formation
