Background

Methylation of DNA at cytosine residues plays an important role in regulation of gene expression, genomic imprinting and is essential for mammalian development. Hypermethylation of CpG islands in tumor suppressor genes or hypomethylation of bulk genomic DNA may be linked with development of cancer. To date, 3 families of mammalian DNA methyltransferase genes have been identified which include Dnmt1, Dnmt2 and Dnmt3. Dnmt1 is constitutively expressed in proliferating cells and inactivation of this gene causes global demethylation of genomic DNA and embryonic lethality. Dnmt2 is expressed at low levels in adult tissues and its inactivation does not affect DNA methylation or maintenance of methylation. The Dnmt3 family members, Dnmt3a and Dnmt3b, are strongly expressed in ES cells but their expression is down regulated in differentiating ES cells and is low in adult somatic tissue. Recently, it has been shown that naturally occurring mutations of Dnmt3b gene occurs in patients with a rare autosomal recessive disorder, termed ICF (immunodeficiency, centromeric instability, and facial anomalies) syndrome.

Data

Western blot analysis of DNMT3A expression in MEF (A), H9C2 (B), HCT116 (C), Jurkat (D), PC3 (E), HEK293T (F) whole cell lysates. (Predicted band size: 16; 81; 101 kD; Observed band size: 130 kD)

Immunohistochemical analysis of DNMT3A staining in human colorectal 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.

Storage

Shipped at 4℃. Store at -20℃ for one year. Avoid repeated 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.
