Background: Component of the post-replicative DNA mismatch repair system(MMR). Heterodimerizes with MLH1 to form MutL alpha. DNA repair is initiated by MutS alpha(MSH2-MSH6) or MutS beta(MSH2-MSH6) binding to a dsDNA mismatch, then MutL alpha is recruited to the heteroduplex. Assembly of the MutL-MutS-heteroduplex ternary complex in presence of RFC and PCNA is sufficient to activate endonuclease activity of PMS2. It introduces single-strand breaks near the mismatch and thus generates new entry points for the exonuclease EXO1 to degrade the strand containing the mismatch. DNA methylation would prevent cleavage and therefore assure that only the newly mutated DNA strand is going to be corrected. MutL alpha(MLH1-PMS2) interacts physically with the clamp loader subunits of DNA polymerase III, suggesting that it may play a role to recruit the DNA polymerase III to the site of the MMR. Also implicated in DNA damage signaling, a process which induces cell cycle arrest and can lead to apoptosis in case of major DNA damages.

How many times can antibodies be recycled?

First, usually it's not suggested to recycle antibodies. After use, buffer system of antibodies has changed. The storage condition of recycled antibodies for different customers also varies. Thus, the performance efficiency of recycled antibodies can’t be guaranteed. Besides, FineTest ever conducted the antibody recycling assay. Assay results show recycling times of different antibodies also varies. Usually, higher antibody titer allows more repeated use. Customers can determine based on experimental requirements.

Notes: After incubation, we recycle rest antibodies to centrifuge tube and store at 4℃. High titer antibodies can be stored for a minimum of one week. Reuse about three times.

What are components of FineTest antibody buffer?

Components of FineTest antibody buffer are usually PBS with proclin300 or sodium azide, BSA, 50% glycerol. Common preservative is proclin300 or sodium azide, which is widely applied in the lab and industry.

How about the storage temperature and duration of FineTest antibodies?

Most antibodies are stored at -20℃. Directly-labeled flow cytometry antibodies should be stored at 2 - 8℃. The shelf life is one year. If after sales issues for purchased antibodies appear, return or replacement is available. Usually, antibodies can be still used after the one-year warranty. We can offer technical support services.

Is dilution required for FineTest antibodies? What’s the dilute solution?

Directly-labeled flow cytometry antibodies are ready-to-use without dilution. Other antibodies are usually concentrated. Follow the dilution ratio suggested in the manual. Dilute solution for different experiments also varies. Common antibody dilution buffers are acceptable(e.g. PBST, TBST, antibody blocking buffer).

How to retrieve antibodies for immunohistochemistry?

Common retrieval buffers: Tris-EDTA Buffer(pH 9.0); Citrate Buffer(pH 6.0)

Heat induced antibody retrieval:

Method 1: Water-bath heating: Put the beaker with retrieval buffer and slide in the boiling water bath. Keep the boiling state for 15min. Naturally cool to room temperature;

Method 2: Microwave retrieval: Put the beaker with retrieval buffer and slide in the microwave oven. Heat at high power for 5min, Switch OFF for 3min, Heat at medium power for 5min. Naturally cool to room temperature.

How to choose secondary antibodies?

(1) Secondary antibodies react with primary antibodies. Thus, secondary antibodies should be against host species of primary antibodies. E.g. If the primary antibody is derived from rabbit, the relevant secondary antibody should be against rabbit. E.g. goat anti rabbit or donkey anti rabbit.

(2) Choose secondary antibody conjugates according to the experimental type, e.g. ELISA, WB, IHC etc. Common enzyme conjugated secondary antibodies are labelled by HRP, AP etc. Fluorescin or dye labelled secondary antibodies are applied in immunofluorescence and flow cytometry(e.g. FITC, Cy3).
