Additional Information:
Tissue Type: Islets
Fixation: Formalin fixed paraffin sections
Positive Control: alpha cells in islets
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
