Summary and Explanation
TintoFast HMB45 reacts against an antigen present in immature melanosomes, cutaneous melanocytes, prenatal and infantile retinal pigment epithelium and melanoma cells. This antibody was generated to an extract of Melanoma. It reacted positively against Melanocytic Tumors but not other tumors, thus demonstrating specificity and sensitivity. Moreover, this antibody reacts positively against junctional nevus cells but not intradermal nevi, and against fetal melanocytes but not normal adult melanocytes.
TintoFast HMB45 antibody is very useful to identify Malignant Melanoma. Metastatic Amelanotic Melanoma can often be confused with a variety of poorly differentiated Carcinomas, Large Cell Lymphomas, Sarcomas, Spindle Cell Carcinomas and various types of mesenchymal neoplasms. A keratin-negative, vimentin-rich neoplasm that immunoreacts with antibody to S-100 protein and with this melanoma antibody, is, with rare exception, not a Melanoma.
Presentation
TintoFast HMB45 is a mouse monoclonal antibody derived from cell culture supernatant that is concentrated, dialyzed, filter sterilized and diluted in buffer pH 7.5, containing BSA and sodium azide as a preservative.
Mohs IHC Procedure
Specimen Preparation of Mohs Frozen Tissues
- Embed the specimen in OCT inside a cryostat.
- Cut sections at 4-5 µm and mount on a positively charged glass slide such as the Bio SB Hydrophilic Plus Slides (BSB 7028) or in the lower third of the TintoDetector Cap Gap slides (BSB 7006).
- Air dry the slide at room temperature for 2 minutes and then incubate the slide at 60 °C for 3 minutes in an incubator or dry bath.
- Fix in 100% acetone for 2 minutes at room temperature.
Pretreatment of Mohs Frozen Tissues
- Preheat the TintoDetector Incubator to 110°C.
- Place TintoDetector Cap Gap slides (BSB 7006) face to face and insert them into the TintoDetector Slide Holder (BSB 7003).
- Submerge slides in ImmunoDNA Retriever with EDTA to draw up enough solution by capillary action to cover the tissues.
- Heat the slides in a preheated TintoDetector Incubator for 3 minutes.
- Transfer slides to room temperature and cool off for 1 min.
Mohs IHC Detection
- After HIER, transfer slides to ImmunoDNA washer and let it stand for 1-2 minutes.
- For manual staining, perform antibody incubation at ambient temperature. For automated staining methods, perform antibody incubation according to instrument manufacturer’s instructions.
- Wash slides with ImmunoDNA washer or DI water.
- Continue IHC detection protocol. Wash slides between each step with ImmunoDNA washer solution.
