Target

  • Relevance

    Human IgA (immunoglobulin A) is a glycosylated protein of 160 kDa and is produced as a monomer or as a J chain linked dimer. Monomeric IgA constitutes 5-15 % of the serum immunoglobulins whereas dimeric IgA is localized to mucosa surfaces such as saliva, gastrointestinal secretion, bronchial fluids and milk. Mucosal IgA plays a major role in host defence by neutralising infectious agents at mucosal surfaces. The production is usually local and antigen specific IgA producing B cells can be found in regions under the lamina propria where they mature into dimeric IgA producing plasma cells. IgA deficiency is the most common immunodeficiency that may affect both serum and mucosal produced IgA. OR: The secretory component is a component of immunoglobulin A (IgA) which consists of a portion of the polymeric immunoglobulin receptor. Polymeric IgA binds to the polymeric immunoglobulin receptor on the basolateral surface of epithelial cells and is taken up into the cell via transcytosis. The receptor-IgA complex passes through the cellular compartments before being secreted on the luminal surface of the epithelial cells, still attached to the receptor. Proteolysis of the receptor occurs and the dimeric IgA molecule, along with the secretory component, are free to diffuse throughout the lumen.

Answer

Thank you for your phone call. I did some research regarding PVA and found that for unknown reasons, PVA does not seem to effectively block background in WB. You may need to switch to BSA or milk in order to get clear bands in addition to the new secondary I am sending.
As requested, I have issued a free of charge replacement with the order number 1203530.

Regarding ab24070, the datasheet does indicate that B mercaptoethanol destroys the epitope, so you will need to be careful to avoid this reagent when blotting for Mucin 5AC.

To check the status of the order please contact our Customer Service team and reference this number.

Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let us know.

I wish you the best of luck with your research.

Answer

Thank you for contacting us. Looking at your blots I think there is a few things you can try. One is to decrease the secondary antibody dilution. Since the blots are all the same it indicates some nonspecific binding. You can also add a no primary control to see if there is non-sepcific binding from the secondary alone. You can also increase your blocking time (even overnight at 4 degrees) or switch your blocking agent from milk to BSA or vice versa to see if this reduces background. Normally the primary antibody dilution for a WB when using a purified antibody can be about 1 ug/ml, however since the pattern is the same for all three different antibodies I am not convinced this is a primary antibody problem. Please let me know if these suggestions don't improve your results.
