Specificity was tested by blocking with peptide used for immunization, by Western blot analysis with HRS cell lines and positive controls from supplier, and by staining in a positive control.
NA indicates not applicable; ND, not done; PC, pressure cooking for 1 minute at 121°C in 1 mM EDTA (ethylenediaminetetraacetic acid) pH 8.0; MWO, 15 or 30 minutes in a microwave oven at maximum power in 600 mL of 10 mM Na citrate pH 6.0.
Suppliers were as follows: Santa Cruz Biotechnology, Santa Cruz, CA; Dianova, Hamburg, Germany; Genex Bioscience, Hayward, CA; Oncogene, Boston, MA; Acris, Hiddenhausen, Germany; Abcam, Cambridge, United Kingdom; Zymed, San Francisco, CA; Upstate, Waltham, MA; Sigma, Munich, Germany.
All incubations were performed at room temperature
As stated by the supplier, this antibody should also react with TRKB and TRKC. However, in WB, the KMH2 cell line, which showed a strong signal for TRKB expression in the microarray analysis, was negative. Therefore, we regarded this anti-TRK antibody as TRKA specific
