Begin with immunohistochemistry (IHC) or whole-mount immunofluorescence using optimized fixation protocols (typically 4% paraformaldehyde for 1-4 hours depending on tissue type) and antigen retrieval methods if necessary. For developmental studies, collect tissues at defined developmental stages (e.g., 4, 7, 14, 21 days after germination) or following specific treatments or environmental stimuli. Complement imaging approaches with quantitative Western blot analysis of protein extracts from isolated tissues, normalizing expression to stable reference proteins like actin-7, which has been well-characterized in Arabidopsis . Create expression profiles by systematically analyzing tissues including roots, stems, leaves, flowers, and seeds. For enhanced spatial resolution, combine antibody-based detection with laser capture microdissection to isolate specific cell types before protein extraction. This integrated approach allows for both visualization of subcellular localization and quantification of expression levels across tissues and developmental stages .

What factors might contribute to inconsistent Western blot results with At5g07610 Antibody?

Inconsistent Western blot results with At5g07610 Antibody can stem from multiple factors throughout the experimental workflow. First, protein extraction conditions significantly impact results; variations in buffer composition, extraction temperature, or mechanical disruption methods can affect protein yield and integrity.
