WB; IH,Frozen; IH(P), Paraffin Immunohistochemistry (IHC) and Western Blotting (WB). A concentration of 2.0 µg/mL is recommended for WB. Human Cadherin-2 (precursor) has a predicted length of 906 residues and MW of 100 kDa. A concentration of 4.0 µg/mL is recommended for IHC to detect the protein in formalin/acetone fixed tissues. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
