Solarbio By Kossa 칼슘 스테인 키트

키트 구성품

소개

Calcium is abundant in the human body, forming bones as a scaffold to support it. Calcium plays a crucial role in secretion, 운송, muscle contraction, nerve conduction, 그리고 더. Several dyes can form chelates with calcium, such as Alizarin Red 5, Purpurin, Nuclear Fast Red, 등. Alizarin Red S, a sodium alizarin sulfonate, is an anthraquinone derivative capable of chelating with calcium carbonate or calcium phosphate to form an orange-red complex. Common methods for calcium salt staining include the Von Kossa method and the Alizarin Red S method. This kit’s principle relies on a metal replacement method: when Von Kossa Silver Solution acts on sections containing insoluble calcium salt, calcium is replaced by silver, and the silver salt reduces to black metal silver under light exposure. It’s suitable for calcium salt tissue staining of numerous samples.

규약 (참고용으로만)

1. Fix the tissue with 10% NBF and conventionally dehydrate and embed.
2. Cut the section into 5µm, conventionally dewax and hydrate.
3. Dye the section with Von Kossa Silver Solution under strong light for 15–60 minutes.
4. Rinse with distilled water for 1 분. Treat with Hypo Solution for 2 분.
5. (선택 과목) Re-dyeing with HE solution or Van Gieson Solution.
6. Conventionally dehydrate, transparent, 그리고 레진으로 밀봉하세요.

부정적인 제어 (선택 과목)

Take another adjacent section and dewax it to water. Put it into Von Kossa Control Solution for 20 분, then rinse it with running water for 5 분. 그후, place it into Von Kossa Silver Solution together with the experimental section, and follow the same steps as above.

결과

메모

1. It’s best to use NBF for fixing tissues containing calcium salt.
2. The action time depends on the intensity and duration of light exposure.
3. If exposed to UV light, reduce exposure time to 5-10 분.
4. 안전과 건강을 위해, wear experimental clothing and disposable gloves
