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 Primary Antibody Enhancer (TL-060-PB), 60mL HRP Polymer (TL-060-PH)
TL-125-HL: 125mL Ultra V Block (TA-125-UB), 125mL Primary Antibody Enhancer (TL-125-PB), 125mL HRP Polymer (TL-125-PH)
UltraVision detection system detects a specific mouse IgG or rabbit IgG antibody bound to an antigen in tissue sections. The specific antibody is located by a universal secondary antibody formulation conjugated to an enzyme-labeled polymer that recognizes mouse and rabbit immunoglobulins. The polymer complex is then visualized with an appropriate substrate/chromogen.
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 minutes.
6. Wash 4 times in buffer.
7. 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 Primary Antibody Enhancer and incubate for 10 minutes at room temperature.
12. Wash 4 times in buffer.
13. Apply HRP Polymer and incubate for 15 minutes at room temperature. (NOTE: HRP Polymer is light sensitive. Please avoid unnecessary light exposure and store in opaque vial.)
14. Wash 4 times in buffer.
15. Incubate with peroxidase-compatible chromogen of choice according to manufacturer's recommendations. Modify incubation time to optimize staining in your laboratory.
16. Wash 4 times in DI water.
17. 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:
