DTX45 Antibody

What is DTX45 Antibody and what is its primary research application?

DTX45 Antibody is an immunological reagent used in research applications related to Deltex family proteins. While specific information about DTX45 is limited in the literature, it likely functions similarly to other DTX family proteins such as DTX4, which regulates Notch signaling pathways involved in cell-cell communications and cell-fate determinations . Primary research applications include western blotting, immunohistochemistry, and flow cytometry for detecting DTX45 protein expression in experimental systems.

What are the optimal storage conditions for DTX45 Antibody?

Most antibodies in this class, including DTX45 Antibody, should be stored at -20°C and protected from repeated freeze-thaw cycles to maintain reactivity and specificity . For short-term storage (1-2 weeks), antibodies can be kept at 4°C. Antibody solutions typically contain preservatives such as sodium azide (0.09%) to prevent microbial contamination during storage . Always refer to the manufacturer's recommendations for specific storage guidelines.

What positive controls are recommended for validating DTX45 Antibody specificity?

When using DTX45 Antibody, positive controls should be selected based on known expression patterns. For DTX family proteins, human cell lines such as K562 (chronic myelogenous leukemia) and SW13 (adrenal cortex adenocarcinoma) have been demonstrated to express detectable levels of related proteins like DTX1/DTX4 . These cell lines may serve as appropriate positive controls for initial validation studies of DTX45 Antibody, though experimental confirmation is necessary.

How should researchers optimize DTX45 Antibody dilution for different applications?

As noted in related antibody documentation, "Optimal dilutions should be determined by each laboratory for each application" . This typically involves performing a dilution series experiment to identify the concentration that provides maximum specific signal with minimal background.

What sample preparation protocols are most effective for DTX45 detection in different cellular compartments?

Based on research with related DTX family proteins, different extraction methods are recommended depending on the cellular localization being investigated:

For cytoplasmic DTX45 (similar to DTX4 localization patterns ):
