Product introduction:
After cells or tissues are fixed with paraformadehyde, formalin or other aldehyde reagents, the antigenic determinants form aldehyde bonds, carboxymethyl bonds, and cross-links in protein detection, etc., which cause changes in the spatial structure of the protein and make the antigen The determinants are blocked, and the binding points of antigen and antibody are reduced, which eventually leads to a relatively weakening of the positive detection rate and staining intensity of the antigen during immunolabeling, which manifests as false negative or low positive rate. The cross-linking of proteins caused by aldehydes is reversible. Under certain conditions, such as high temperature or protease hydrolysis, the original conformation of the protein can be restored. This process is called antigen retrieval. Antigen retrieval is a key step that cannot be ignored in the process of immunohistochemistry. There are many antigen retrieval methods. Different methods can be selected according to the characteristics of tissue types. Some are suitable for thermal repair, and some are suitable for enzymatic repair. Before the heat-induced antigen retrieval method appeared, the epitope retrieval induced by trypsin, proteinase K, pepsin and other enzymes was the most commonly used method.
This product is a pepsin antigen retrieval solution, the pepsin concentration is 0.4%, the solvent is dilute hydrochloic acid, and the solution is acidic. Can be used for the repair of interstitial antigens.
Package Contents:
Storage conditions:
Ice packs transportation, store at 4°C, store at -20°C when not in use for a long time to avoid repeated freezing and thawing. The validity period is 12 months.
Instructions
In the experimental steps of immunohistochemistry or immunofluorescence, in the antigen retrieval step, directly add the pepsin antigen retrieval solution to the tissue slides to cover the tissue, or soak the slides in the repair solution and incubate at 37°C for 10-30 mins. The specific time is adjusted according to the repair effect of the slides .
Precautions
1. The pepsin antigen retrieval solution should be restored to room temperature before use.
2. In order to obtain the best experimental results, the optimal incubation time for antigen retrieval is recommended to be pre-experimented based on different samples and target proteins.
3. The pepsin antigen retrieval solution is acidic, which may cause poor tissue morphology on the slides. Please pay attention to the incubation time.
4. For your safety and health, please wear lab coats and disposable gloves during operation.
