Desmin Antibody Staining Protocol for Immunohistochemistry


Description: The antibody reacts with desmin from human, pig, rat and taod. In tissue sections this antibody is used to stain skeletal, cardiac, visceral, and some vascular smooth muscle cells. Cell lines such as RD (ATCC CCL 136) and hamster BHK-21 are positive.

Additional Information:
Tissue Type: Skin, skeletal muscle, cardiac tissue (heart), GI tract (stomach, intestine, colon).
Fixation: Formalin fixed paraffin sections, or acetone fixed frozen sections
Positive Control: Skin, skeletal muscle, cardiac tissue (heart), GI tract (stomach, intestine, colon).
Negative Control: Omit primary antibody, isotype control or absorption control
Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary


No need to perform antigen retrieval on frozen sections
