    • ab54217 staining human peripheral blood lymphocytes by FACS analysis.
    • ab54217 staining cultured human bone marrow stem cells by ICC/IF. Cells were formaldehyde fixed, permeabilization not done prior to blocking in 1% BSA for 30 minutes at 22°C. The primary antibody was diluted 1/250 and incubated with sample for 12 hours at 4°C. FITC conjugated rabbit polyclonal to mouse diluted 1/1000 was used as the secondary.

    Merci de nous avoir contactés et désolé pour le délai de ma réponse.
    Je viens d'être informé que l'anti-CD73 clone [7G2] (référence ab54217) a été décrit pour des tests d'inhibition dans la publication suivante : Thomson LF, et al. Tissue Antigens 35(1):9-19, 1990. Je n'ai malheureusement pas accès à cet article et ne peut donc pas vous donner plus de détails sur le protocole utilisé.
    Nous ne fournissons pas cette référence sans conservateur dans le tampon.
    J'espère que ces informations vous seront utiles. N'hésitez pas à nous contacter de nouveau si vous avez d'autres questions.

    Thank you for your reply.

    For dilution of the antibodies ready to use in the experiment, as discussed in the previous email I can suggest to dilute antibodiesin PBS orTBS. It is sometimes helpful to include 0.2% Tween 20, however this may need to be optimized individually. If there is high background staining, then 2 to 5% blocking agent can also be included.

    You may like to consider reviewing our online protocols from our Scientific support protocols and troubleshooting pages. IHC documents are under Immunostaining. These will contain some further information that I hope may be helpful:
