Performed under reducing conditions.

Predicted band size : 93 kDa
Observed band size : 95 kDa (why is the actual band size different from the predicted?)
Additional bands at : 180 kDa,60 kDa (possible cleavage fragment),70 kDa (possible cleavage fragment). We are unsure as to the identity of these extra bands.

Exposure time : 15 seconds

LCL1, LCL2, and LCL3 are three patient derived fibroblast cell lines. The middle band is BRIT1 (denoted by arrow) as determined by treatment with siRNA.

ab2612 staining in human lung, showing staining of the surface epithelial cells (in brown). Paraffin embedded lung tissue was incubated with ab2612 (1:100 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.

ab2612 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues as well as a cell microarray consisting of a range of commonly used, well characterised human cell lines. Further results for this antibody can be found at www.proteinatlas.org

Immunohistochemistry (PFA perfusion fixed frozen sections) - BRIT1 antibody (ab2612)

Immunohistochemistical detection of BRIT1 using antibody (ab2612) on paraformaldehyde perfusion fixed mouse heart tissue sections. Primary antibody diluted @ 1/300 & incubated for 18 hours @ 20°C in PBS + 0.3 % Triton X100. Secondary antibody: goat anti-rabbit conjugated to biotin (1/300).  The antibody produced a weak cytoplasmic staining in cardiac cells.
