What are the key considerations when selecting a CYP71B31 antibody for my research?

When selecting a CYP71B31 antibody for research applications, consider the following methodological factors:

• Immunogen sequence: Verify the exact epitope used to generate the antibody. For CYP family proteins, antibodies raised against unique regions rather than conserved domains offer higher specificity .

• Host species: Consider the host species (rabbit, mouse, goat, etc.) in relation to your experimental design, especially for co-staining experiments or when working with tissue samples.

• Clonality: Polyclonal antibodies generally provide broader epitope recognition but may have batch-to-batch variability, while monoclonal antibodies offer higher consistency and specificity .

• Validated applications: Confirm the antibody has been validated for your specific applications (Western blot, IHC, ICC, IP, etc.) with documented experimental evidence.

• Cross-reactivity profile: Examine cross-reactivity with other CYP family members, particularly those with high sequence homology, to ensure accurate interpretation of results .

These considerations are essential for experimental success and should be evaluated before finalizing your antibody selection.
