ALDH2B7 Antibody

What is ALDH2B7 Antibody and how does it relate to the aldehyde dehydrogenase family?

ALDH2B7 Antibody is a research tool for detecting the ALDH2B7 protein, a member of the aldehyde dehydrogenase (ALDH) family. This family comprises crucial enzymes involved in endogenous aldehyde detoxification that have been implicated in various biological processes including tumor progression and immune evasion . While specific ALDH isoforms like ALDH1A1 have been identified as mediators of resistance to treatments such as temozolomide in glioblastoma , ALDH2B7 Antibody allows researchers to investigate this specific variant's expression patterns and roles in normal and pathological states.

How should researchers validate the specificity of ALDH2B7 Antibody?

Antibody validation is critical for ensuring reliable research results. Based on practices established for other ALDH antibodies, researchers should:

• Perform reverse transcriptase (RT)-PCR to validate specificity against other ALDH isoforms

• Test immunoreactivity in cell lines expressing other ALDH isoforms to confirm lack of cross-reactivity

• Include appropriate positive controls (e.g., tissues known to express ALDH2B7) and negative controls

• Validate reactivity across multiple applications (WB, IF, IHC)

For example, the specificity of anti-ALDH1A1 antibody was validated by confirming that cell lines expressing other isoforms (ALDH1A3, ALDH3A1, ALDH7A1, ALDH8A1, and ALDH2) showed no immunoreactivity with the applied antibody .

What are the recommended applications and protocols for ALDH2B7 Antibody?

Based on established protocols for similar ALDH family antibodies, ALDH2B7 Antibody can be utilized in the following applications:

For Western Blotting specifically, researchers should expect to detect ALDH2B7 at approximately 55-60 kDa, similar to ALDH2 which appears at approximately 56 kDa . For optimal results in IHC applications, heat-induced epitope retrieval may be necessary as demonstrated with other ALDH antibodies .

How should ALDH2B7 Antibody be stored and handled to maintain efficacy?

While specific storage recommendations for ALDH2B7 may vary by manufacturer, following general practices for antibody preservation is advised:
