General Info

  • Alternative names

    • IAP S1
    • Islet-activating protein S1
    • NAD-dependent ADP-ribosyltransferase

  • Relevance

    Pertussis toxin contains five different chains, S1-S5. They are organized into 2 functional subunits: A, composed of S1 (which is toxic) and B, containing S2, S3, S5, and two copies of S4 (B binds to the membrane receptors). Dimers of S2-S4 and S3-S4 are held together by S5

Question

Dear abcam:



We have a customer that like develop a kit of indirect ELISA. He required antigen of Adacel Boost vaccine, in specific

1) fimbrial agglutinogen 2 or fimbriae 2 antigen of Bordetella pertusis

2) pertactin antigen (PRN) is a protein of 69 http://es.wikipedia.org/wiki/Unidad_de_masa_at%C3%B3mica of http://es.wikipedia.org/wiki/Bordetella_pertussis



Do you have that be conjugated with BSA or other carrier the antigens for ELISA? Do you know the quantity aproxi. that the client could use of antigen for each well?

Answer

Thank you for contacting us.

We carry the Bordetella pertussis toxin protein (ab124299: https://www.abcam.com/bordetella-pertussis-toxin-protein-ab124299.html); however, it is unconjugated.

I have attached our protocol book which includes recommendations for antigen coating for indirect ELISA. To summarize, the antigen should be diluted to a final concentration of 20 ug/ml in PBS, and the microtiter plate should be coated with 50ul of the antigen dilution in the top wells of the plate. The plate should then be incubated for 2 hours at room temperature or 4ºC overnight.

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