면역조직화학용 CD44 항체 시약

【제품명 】

IHC 항체 -- CD44

【 포장 사양 】

【용도 】

연구용으로만 사용하십시오. CD44  항체 시약은  면역조직화학적 검출 시스템을 사용하여 FFPE 조직 절편에서 현미경으로 CD44를 정성적으로 식별하는 데 사용하기 위한 것입니다 .

【원칙 】_

IN, LHRMIC4, CDW44, HCELL로도 알려진 CD44는 세포-세포 상호작용, 세포 접착 및 이동에 관여하는 세포 표면 당단백질입니다.  항-CD44는 요로 상피의 비신생물성 변화로부터 요로 상피 암종을 감별하는데 유용할 수 있습니다. 1 차 항체 를 추가 하여 조직 절편에 항원 을 결합시킨 다음 HRP 표지된 2차 항체 결합 1차 항체를 사용하여 2 차 항체 -1 차 항체 - 항원 복합체를 형성합니다 .   When DAB chromogenic solution is added, HRP reacts with enzyme substrate to produce brown insoluble reaction product, which indirectly indicating the existence of antigen. 

【Main components】

Immunoglobulin, antibody diluent

【Storage】

Store at 2～8℃ for 18 months。

【Sample requirements】

FFPE tissues are usually cut into sections as thin as 3～5μm with a microtome. These sections are then mounted onto glass slides that are coated with a tissue adhesive.

【Protocol】

1. Sample preparation：Deparaffinize the slides in xylene Ⅰ, Ⅱ, Ⅲ for 5 minutes；Transfer the slides once through 100%, 100%, 95%, 75% alcohols for 2 minutes respectively. Rinse slides with deionized water for 30 seconds.

2. Blocking：Block endogenous peroxidase activity by incubating sections in 3% H₂O₂ solution at room temperature for 5 minutes to block endogenous peroxidase activity. Rinse the slides with deionized water for 30 seconds.

3. Antigen retrieval：Heat the EDTA Antigen retrieval buffer to 100℃. Then place the slides in the boiled buffer and continue to heat for 15～20 min. Naturally cool down for 30 minutes. Rinse the sample with wash buffer.

4. Primary antibody incubation: Drain the slides. Add primary antibody to tissue, incubate at room temperature for 30 minutes. (use antibody diluent or PBS as control). Wash the slides in PBST for 2 times, 5 minutes for each time. If the Primary antibody is concentrated, please dilute it to RTU(ready to use) according to the information on packing. 

5. Secondary antibody: Drain the slides. Add secondary antibody to tissue and incubate at room temperature for 20 minutes. Wash the slides in PBST for 2 times, 5 minutes for each time.

6. DAB：Drain the slides. Add DAB to the tissue and incubate at room temperature for 5 min. Rinse slides with deionized water.

7. Hematoxylin staining：Drain the slides. Add Hematoxylin to the tissue and incubate at room temperature for 5 minutes. Rinse slides with water. Use the acid solution for differentiation. Rinse slides with water.

8. Dehydrate：Dehydrate the slides in 75%, 95%, 100% alcohols for 2 minutes. Dry the slides. Cover stained tissue with a coverslip using mounting medium.

【Positive localization】

1. Positive localization: membrane.

2. Positive control: tonsil.

【Precautions】

1. Please read the instruction carefully and become familiar with all components of the kit prior to use, Strictly follow the instruction during operation.

2. DO NOT use the kit or any kit component after their.

3. Only trained professionals can use this kit. Please wear suitable lab coat and disposable gloves while handling the reagents.

4. Avoid contact of skin, eyes and mucous membranes with the chemicals.

5. DO NOT pipet by mouth.

6. Unused reagents, used kit and waste must be disposed according to local regulations.
