Dorsomorphin Information And Misconceptions

Paraffin sections were cut at 5?��m thick and were stained with hematoxylin and eosin ��H&E�� (Bancroft and Gamble, 2002) for histological observation. IHC detection of pancreatic tissues with immunolocalization technique for anti-insulin monoclonal antibody was performed as previously described (Hsu et al., 1981). IHC reaction was carried out by using avidin biotin peroxidase method by Nova Castra Laboratories Ltd, UK. Endogenous peroxidase activity was inhibited by incubation with 0.3% H2O2 for 30?min. The sections were blocked with normal goat serum for 1?h to prevent non-specific binding followed by incubation with the primary insulin monoclonal antibody for 1?h at room temperature. The sections were incubated with the secondary antibody (biotinylated anti-mouse IgM) for 30?min. The sections were then incubated with ExtrAvidin (Sigma) for 45?min at 37?��C. Staining was visualized using diaminobenzidine (DAB, Sigma), then slides were washed and counterstained with hematoxylin, cleared, mounted and examined by light microscopy. Finally, the insulin secreting ��-cells cytoplasmic sites of reaction were stained brown and nuclei stained blue. Data were fed to the computer and analyzed using IBM SPSS? software package version 20.0, USA. Data were analyzed using numbers and percentages?��?S.D or S.E. For normally distributed data, comparisons between the eight studied groups were analyzed using F-test (ANOVA) and Post Hoc test (LSD). Significance was obtained at P?
