This antiserum was produced against recombinant rat calbindin D-28k (CB). It crossreacts
with calbindin D-28k from many other species, including human, monkey, rat, mouse chicken
and fish (Fig. 1). In immunoblots it recognizes a single band of approximately 27 -28 kDa. In
samples with very high (10-fold higher than CB) concentrations of the related protein
calretinin, a larger band (29 - 30 kDa) may appear in Western blots. Thus, depending on the
dilution of the antiserum and/or sensitivity of the immunostaining, this other calcium-binding
protein could be also revealed. In case of doubt, we suggest to switch to Swant’s monoclonal
antibody 300 directed against calbindin D-28k, which does not recognize calretinin.
稀釋
Immunohistochemistry: 1:10'000 - 1:20'000 with the avidin-biotin method.
Immunoblots: 1:100 - 1:1'000. We recommend that the optimal dilutions be determined by
titration experiments.
儲存
Make small portions (e.g. 2-5 μl). For long storage, keep at - 80°C (or at least -20°C). For
continuous use, keep at 4°C (with 0.01% Na-azide). Avoid repeated freezing and
thawing.
