  • Function

    May play an important role in B-cell differentiation as well as neural development and spermatogenesis. Involved in the regulation of the CD19 gene, a B-lymphoid-specific target gene.
  • Involvement in disease

    A chromosomal aberration involving PAX5 is a cause of acute lymphoblastic leukemia. Translocation t(9;18)(p13;q11.2) with ZNF521. Translocation t(9;3)(p13;p14.1) with FOXP1. Translocation t(9;12)(p13;p13) with ETV6.

  • PAX5 was immunoprecipitated using 0.5mg Ramos whole cell extract, 5µg of Rabbit polyclonal to PAX5 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Ramos whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab15164.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 42kDa; PAX5

Vielen Dank für Ihren Anruf gestern.

Ich habe für Sie unsere anti Pax5 Antikörper durchgeschaut und muss Ihnen leider mitteilen, dass auch alle polyklonalen mittels Immunogen-Peptiden hergestellt wurden. Diese werden demnach höchstwahrscheinlich auch nur einmal pro Zielprotein binden und keine Amplifikation liefern.

Meines Wissens ist PE ein sehr "helles" Fluorochrom und sollte zum Sortieren gut geeignet sein, obwohl es schnell ausbleicht.

Da Sie Zielproteine im Kern färben, könnte die schwache Färbung daran liegen, dass der sekundäre nicht optimal bindet, da einfach nicht genug Platz ist. Vielleicht kann man das durch Antikörper- Fragmente wie F(ab)2 verbessern.

Bei anti Mum1 Antikörpern haben wir einen, der mit einem Proteinfragment hergestellt worden ist. Aber dass dieser Antikörper an multiplen Stellen bindet und somit das Signal amplifiziert kann ich Ihnen nicht garantieren, da es ja oft ein dominantes Epitop gibt:

Es tut mir leid, dass ich keine positiven Nachrichten für Sie habe und hoffe, diese Information ist dennoch hilfreich.
