Anti-Gram Positive Bacteria antibody [BDI380] (ab20344)

Thank you for contacting us.


This antibody has not been tested in agglutination applications and we do not suggest using it in such. Per the lab, most antibodies that do function in agglutination are of low affinity. This antibody was developed to produce high affinity.



The lab has suggested the following:

You could try co-agglutination. In this method, the antibody is first bound to killed Staph aureus bacterial suspension by the interaction of protein A that is naturally on the surface of these bacteria. After binding, the bacteria are washed by centrifugation and then resuspended. Now when antigen is added, the Staph aureus suspension agglutinates.
Another alternative to try is to adsorb the antibody to a suspension of latex particles (0.8 micron). After an absorption period, the latex is washed by centrifugation and resuspended. Now when antigen is added, the latex suspension agglutinates.



We cannot guarantee these methods will work, but it may be worth trying them.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for confirming the catalog number.

I am pleased to provide the following information:

1. I am sorry to confirm that ab20344Gram Positive Bacteria antibody [BDI380]has not been tested with P. acnes.

2. This monoclonal antibody reacts with the cell wall of various gram positive bacteria, so therefore it will not stain intracellular. When using this monoclonal in ELISA or colloidal gold conjugated assays, the samples do not need to be fixed and permeabilize with acetone, only when performing Immunofluorescence assays.

I hope this answers your questions and will be helpful to you. If you have any further questions, please do not hesitate to contact us.
