Recombinant Uncharacterized protein T25D10.1 (T25D10.1)

What is T25D10.1 protein and what are its basic properties?

T25D10.1 is an uncharacterized protein from the nematode Caenorhabditis elegans, a model organism widely used in developmental biology, cell biology, and neurobiology research. The protein consists of 327 amino acids (full length) and has the UniProt accession number Q10017 . Its amino acid sequence begins with MFLRRRNLNSSRIICIISIIVLLLIIISLYPHKR and continues through to DMFPKNRTANQEDYFPPKWKKLSRKIQ . Despite being uncharacterized, researchers continue to investigate its potential functions using various experimental approaches.

How should recombinant T25D10.1 protein be stored for optimal stability?

For optimal stability, store recombinant T25D10.1 protein at -20°C for regular use, or at -80°C for extended storage periods . The protein is typically provided in a Tris-based buffer with 50% glycerol optimized for this specific protein . To maintain activity, avoid repeated freeze-thaw cycles as these can cause protein degradation. For ongoing experiments, prepare working aliquots that can be stored at 4°C for up to one week . This storage approach helps preserve structural integrity and biological activity for experimental procedures.

How should experiments be designed to characterize the function of uncharacterized T25D10.1?

When designing experiments to characterize T25D10.1, employ a multi-faceted approach that combines bioinformatic prediction with wet lab validation:

• Independent and dependent variables: Clearly define variables in your experimental design. For T25D10.1 functional studies, the independent variable might be experimental conditions (e.g., presence/absence of potential interacting proteins), while the dependent variable would be a measurable outcome like protein activity or cellular phenotype3.

• Control design: Include both positive and negative controls to validate experimental outcomes. For T25D10.1, this might involve:

  • Negative control: Buffer-only or irrelevant protein treatments

  • Positive control: A well-characterized protein from C. elegans with known function

• Within-subject vs. between-subject design: For cellular assays, consider whether a within-subject design (testing multiple conditions on the same cell population) or between-subject design (testing different conditions on separate populations) is more appropriate .

• Sample size calculation: Determine appropriate sample size based on expected effect size, statistical power considerations, and variability in preliminary data .

What expression systems are most suitable for producing recombinant T25D10.1?
