Specificity: anti-Mouse IgG (H+L), anti-Rabbit IgG (H+L)
Enzyme: Alkaline Phosphatase
Chromogen/Substrate: None provided
TL060AL: Ultra V Block (Mfr. No. TA-060-UB), Primary Antibody Enhancer (Mfr. No. TL-060-PB), AP Polymer (Mfr. No. TL-060-AP)
TL125AL: Ultra V Block (Mfr. No. TA-125-UB), Primary Antibody Enhancer (Mfr. No. TL-125-PB), AP Polymer (Mfr. No. TL-125-AP)
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. 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.)
6. Wash (Optional).
7. Apply primary antibody and incubate according to manufacturer's recommended protocol.
8. Wash 4 times in buffer.
9. Apply Primary Antibody Enhancer and incubate for 20 minutes at room temperature.
10. Wash 4 times in buffer.
11. Apply AP Polymer and incubate for 30 minutes at room temperature.
12. Wash 4 times in buffer.
13. Incubate with phosphatase-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:
