What is Os05g0446300 and why is it important in rice research?

Os05g0446300 (LOC_Os05g37390) encodes a 145-amino acid protein in rice (Oryza sativa) known as Protein BUD31 homolog 2 or Protein G10 homolog 2. This protein belongs to the highly conserved BUD31/G10 family that is implicated in RNA processing and cell cycle regulation across species. Understanding its function is critical for rice developmental biology and potentially for agricultural applications. Research with specific antibodies allows for protein detection, localization studies, and functional characterization in different rice varieties and under various environmental conditions .

What types of antibodies are available for Os05g0446300 detection?

Several region-specific mouse monoclonal antibodies are available for Os05g0446300 detection. These include:

• N-terminus targeting antibodies (X-Q65WT0-N): A combination of monoclonal antibodies against synthetic peptides representing the N-terminal sequence

• C-terminus targeting antibodies (X-Q65WT0-C): Monoclonal antibodies targeting the C-terminal region

• Middle-region targeting antibodies (X-Q65WT0-M): Monoclonal antibodies specific to non-terminal sequences

Each antibody combination has been tested for ELISA applications with reported titers of approximately 10,000, corresponding to detection sensitivity of approximately 1 ng of target protein in Western blot applications .

How do I determine which Os05g0446300 antibody region specificity is appropriate for my experimental question?

The choice of antibody region specificity depends on your experimental goals:

• N-terminal antibodies (X-Q65WT0-N): Ideal for detecting full-length protein and distinguishing it from C-terminal degradation products. These are recommended for studying protein stability and turnover.
