Specificity: anti-Mouse IgG (H+L), anti-Rabbit IgG (H+L)
Chromogen/Substrate: None provided
TL-060-HL: 60mL Ultra V Block (TA-060-UB), 60mL UltraVision ONE HRP Polymer (TL-060-PHJ)
TL-125-HL: 125mL Ultra V Block (TA-125-UB), 125mL UltraVision ONE HRP Polymer (TL-125-PHJ)
UltraVision ONE HRP polymer detection system detects rabbit and mouse immunoglobulins bound to an antigen in tissue sections. The specific primary antibody is located by a universal secondary antibody polymer formulation. The amino acid polymer is conjugated to horseradish peroxidase and the Fab fragments of goat anti-rabbit and goat anti-mouse. The polymer complex is then visualized with an appropriate substrate/chromogen.
NOTE: The appropriate controls, especially negative controls, must be included with every manual or automated slide run. The inclusion of negative controls will aid in accurate interpretation of the staining results and help in determining false positives. Refer to the warnings and precaution section for details.
1. Deparaffinize and rehydrate tissue section.
2. Wash 2 times in buffer.
3. If required, incubate tissue in digestive enzyme (or appropriate pretreatment).
4. Wash 4 times in buffer.
5. To reduce nonspecific background staining due to endogenous peroxidase, incubate slide in Hydrogen Peroxide Block for 10-15 minutes.
6. Wash 4 times in buffer.
7. Optional: Apply Ultra V Block and incubate for 5 minutes at room temperature to block nonspecific background staining.
NOTE: Do not exceed 10 minutes or there may be a reduction in desired stain. (May be omitted if primary antibodies are diluted in buffers containing 5-10% normal goat serum.)
8. Wash (Optional).
9. Apply primary antibody and incubate according to manufacturer's recommended protocol.
10. Wash 4 times in buffer.
11. Apply UltraVision ONE HRP Polymer and incubate for 30 minutes at room temperature. (NOTE: HRP Polymer is light sensitive. Please avoid unnecessary light exposure and store in opaque vial.)
12. Wash 4 times in buffer.
13. Incubate with peroxidase-compatible chromogen of choice according to manufacturer's recommendations. Modify incubation time to optimize staining in your laboratory.
14. Wash 4 times in DI water.
15. Counterstain and cover slip using an aqueous mounting media.
The specificity and sensitivity of antigen detection is dependent on the specific primary antibody used. General References:
