Product Details

Background

May act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. Plays a role in embryonic stem cells proliferation and differentiation. Up-regulates the expression of FABP5, MYC and cyclins A and E.

Application

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

Data

All lanes: Anti-EpCAM antibody at 1:2,000 dilution
Predicted MW: 35 kDa
Observed MW: 40 kDa

Lane 1: HT-29
Lane 2: T47D

Lysate at 10 µg per lane
2nd Ab:
GAR HRP(H+L) 1:5,000
Exposure: 50s

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human uterus tissue labelling EpCAM with ARA801 at 1:3,200. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9.0.

Overlay histogram showing HCT-116 cells stained with ARA801 (Red). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% TritonX-100 for 15 min. The cells were then incubated in the antibody (ARA801, 1:800 dilution) in 1x PBS/1% BSA for 30 min at room temperature. The secondary antibody used was a Goat Anti-Rabbit Alexa Fluor<sup>®</sup> 488 (IgG H+L) at 1:2,000 dilution for 20 min at room temperature. Unlabelled sample (Black) was used as a control.

EpCAM was immunoprecipitated from 0.4mg of HT-29 whole cell lysate with ARA801 at 1:50 dilution.
2nd Ab:
GAR HRP for IP 1:500

Lane 1: ARA801 IP in HT-29 whole cell lysate
Lane 2: PBS instead of ARA801 in HT-29 whole cell lysate
Lane 3: HT-29 whole cell lysate, 10 µg (input)
Exposure: 120s

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.
