- Background
- Atypical E2F transcription factor that participates in various processes such as angiogenesis, polyploidization of specialized cells and DNA damage response. Mainly acts as a transcription repressor that binds DNA independently of DP proteins and specifically recognizes the E2 recognition site 5'-TTTC[CG]CGC-3'. Directly represses transcription of classical E2F transcription factors such as E2F1. Acts as a regulator of S-phase by recognizing and binding the E2-related site 5'-TTCCCGCC-3' and mediating repression of G1/S-regulated genes. Plays a key role in polyploidization of cells in placenta and liver by regulating the endocycle, probably by repressing genes promoting cytokinesis and antagonizing action of classical E2F proteins(E2F1, E2F2 and/or E2F3). Required for placental development by promoting polyploidization of trophoblast giant cells. Also involved in DNA damage response: up-regulated by p53/TP53 following genotoxic stress and acts as a downstream effector of p53/TP53-dependent repression by mediating repression of indirect p53/TP53 target genes involved in DNA replication. Acts as a promoter of sprouting angiogenesis, possibly by acting as a transcription activator: associates with HIF1A, recognizes and binds the VEGFA promoter, which is different from canonical E2 recognition site, and activates expression of the VEGFA gene. Acts as a negative regulator of keratinocyte differentiation.
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).
