Product Details

Background

Transcriptional regulator which controls the expression of hepatic genes during the transition of endodermal cells to hepatic progenitor cells, facilitating the recruitment of RNA pol II to the promoters of target genes . Activates the transcription of CYP2C38 . Represses the CLOCK-BMAL1 transcriptional activity and is essential for circadian rhythm maintenance and period regulation in the liver and colon cells .

Application

To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.

WB	1:500 - 1:1000
IHC	1:100 - 1:200
IF/ICC	1:100 - 1:500

*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

Data

Western blot analysis of HNF4 alpha (Phospho-S313) expression in HepG2 (A), LO2 (B), C6 (C), CY26 (D) whole cell lysates. (Predicted band size: 52 kD; Observed band size: 52 kD)

Immunohistochemical analysis of HNF4 alpha (Phospho-S313) staining in human colon cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Immunofluorescent analysis of HNF4 alpha (Phospho-S313) staining in SW480 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark.

Direct ELISA antibody dose-response curve using Anti-HNF4 alpha (Phospho-S313) Antibody. Antigen (Phosphopeptide and non-phosphopeptide) concentration is 5 ug/ml. Goat Anti-Rabbit IgG (H&L) - HRP was used as the secondary antibody, and signal was developed by TMB substrate.

Storage

Store at 4°C short term. For long term storage, store at -20°C, avoiding freeze/thaw cycles.

FAQs

What are the main types of research antibodies and how do they differ?

Research antibodies are mainly divided into monoclonal antibodies and polyclonal antibodies. Monoclonal antibodies typically offer higher specificity and better batch-to-batch consistency, while polyclonal antibodies often provide stronger affinity but may show more variation between batches. The choice depends on your specific experimental needs.

How can I tell if a research antibody is suitable for my experiment?

It is recommended to carefully review the product datasheet for validated applications, species reactivity, recommended dilutions, and published references. For new antibodies, performing a small-scale validation with positive control samples is usually helpful.

Can improper storage of research antibodies affect experimental results?

Yes. Antibodies are sensitive to temperature, repeated freeze-thaw cycles, and contamination. Improper storage may lead to reduced activity, increased background, or weaker signals. It is best to follow the storage instructions provided in the product datasheet.

Why doesn’t the recommended dilution in the datasheet work well in my experiment?

The recommended dilution is based on the supplier’s test conditions. Factors such as sample type, fixation method, and detection system in your lab can influence the optimal working concentration. Performing a dilution series optimization in your own system is often necessary.

What precautions should I take when using a newly purchased research antibody for the first time?

It is advisable to briefly centrifuge the antibody (especially concentrated or lyophilized ones), then perform a small-scale pilot experiment using the recommended conditions. Recording the batch number and usage date is also helpful for future tracking.
