General notes
Normal donkey serum ab7475 is used extensively for the blocking of non-specific antibody binding in tissue and cell staining, and in other applications of antibodies.
The donkey serum blocks the binding of Fc receptors in the sample to the primary and secondary antibodies used in the experiment, and also blocks non-specific binding of the antibodies to the sample.
Typically the serum used for blocking is from a different species than the species in which the primary antibody was raised. Often the blocking serum is from the species in which the secondary antibody was raised.
Serum can be used directly for blocking, or as a constituent of a blocking buffer.
Strain: Mixed breed and sex.
Raised in: Donkey

Functional Studies - Normal Donkey Serum (ab7475)Paul, Rajib et al., PloS one vol. 12,2 e0171285., Fig 5, doi:10.1371/journal.pone.0171285The sections were rinsed three times with 0.1 M Tris-buffered saline (TBS, 0.1 M; pH 7.4), incubated in 3% H2O2 in TBS, permeabilized with 0.3% Triton X-100, and blocked with 10% donkey serum containing 0.3% Triton X-100. The sections were incubated overnight with primary antibody for TH (1:700) in TBS, containing 2% donkey serum (ab7475) at 4°C and then incubated with HRP-conjugated secondary antibody (1:1000) in TBS for 1 h at room temperature.
