Target

  • Relevance
    Staphylococcus aureus are gram-positive bacteria that, although part of the normal flora of humans (nasal passages, skin and mucous membranes), have the potential to become opportunistic pathogens. S. aureus is a frequent cause of a wide range of infections and some bacterial strains have become resistant to many commonly used antibiotics.
  • Alternative names
    • S. aureus antibody

  • ab20920 staining Staphylococcus aureus in human keratinocytes by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed in methanol, permeabilized using 0.1% saponin/ PBS, blocked with 4% BSA for 30 minutes at 25°C and then incubated with ab20920 at 10µg/ml for 14 hours at 4°C. The secondary used was an Alexa-Fluor 488 conjugated goat anti-rabbit polyclonal used at a 1/100 dilution.

The Hamza and Li publication BMC Microbiol 14:207 (2014) cites ab20920 as detecting the ATCC 25923 strain so there is evidence it will cross react.

The cells used for the immunogen started out as whole cells that were disrupted by sonication and freeze/thaw cycles. Therefore the immunogen is a mixture of intact Staph aureus organisms and soluble proteins from disrupted cells. This is no record of ...

Thank you very much for your email.
There is absolutely no problem, the antibody will still work properly in my opinion.
Indeed, we have tested different antibodies, and even after a week at 37 degrees Celcius, the antibodies did not seem to ...

Thank you for contacting us. Indeed, neither ab68954 nor ab20920 have been tested for immunoprecipitation (IP) yet, but they could theoretically be used in this application. If it is just between the two, I would recommend ab20920 because it is an u...
