Data

Western blot analysis of Cytokeratin 19 expression in T47D (A), MCF7 (B), HepG2 (C), SW620 (D), HT29 (E), HCT116 (F), PC12 (G), C6 (H) whole cell lysates. (Predicted band size: 44 kD; Observed band size: 47 kD kD)

Immunohistochemical analysis of Cytokeratin 19 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.

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.
