YMR265C is a gene/protein in Saccharomyces cerevisiae (Baker's yeast), with the corresponding NCBI GeneID 855307 and accession number NP_013992.1 . It is studied in yeast research as part of understanding fundamental cellular processes. The protein is recombinantly expressed from S. cerevisiae strain 204508/S288c for antibody production . Research with YMR265C contributes to our understanding of yeast biology, which serves as a model organism for eukaryotic cellular processes. Antibodies against YMR265C enable detection and quantification of this protein in various experimental settings.
The YMR265C antibody has been validated for use in ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot applications . These techniques allow researchers to detect and quantify YMR265C protein in experimental samples. Similar to other research antibodies, such experimental approaches enable investigation of protein expression levels, localization, and interactions. Western blotting provides information about protein molecular weight and relative abundance, while ELISA offers more quantitative measurements. Researchers should validate the antibody for additional applications such as immunohistochemistry, immunofluorescence, or immunoprecipitation before use in those contexts.
The YMR265C antibody should be stored at -20°C or -80°C upon receipt to maintain efficacy . Repeated freeze-thaw cycles should be avoided as they can degrade antibody quality. The antibody is formulated in liquid form containing 0.03% Proclin 300 as a preservative, 50% Glycerol, and 0.01M PBS at pH 7.4 . If small volumes become entrapped in the container's cap during shipment or storage, briefly centrifuge the vial on a tabletop centrifuge to recover the liquid . This methodology for preserving antibody function follows standard immunoreagent handling protocols established for research-grade antibodies. Proper aliquoting before freezing can help minimize freeze-thaw cycles when repeatedly accessing the antibody.
When conducting Western blot experiments with YMR265C antibody, researchers should include several controls to ensure valid results:
Positive control: Extract from wild-type S. cerevisiae expressing YMR265C
Negative control: Extract from YMR265C knockout strain
Isotype control: Non-specific rabbit IgG antibody at the same concentration
Loading control: Antibody against a housekeeping protein (e.g., actin, GAPDH)
Recombinant YMR265C protein as a standard
These controls help distinguish specific from non-specific binding and account for technical variations. Similar antibody validation approaches have been used in studies of other yeast proteins and therapeutic antibody research . Researchers should optimize antibody dilution and incubation conditions through titration experiments to achieve the best signal-to-noise ratio.
Validating YMR265C antibody specificity requires multiple complementary approaches:
Genetic validation: Compare signal between wild-type and YMR265C knockout strains
Peptide competition assay: Pre-incubate antibody with immunizing peptide/protein to block specific binding
Cross-reactivity testing: Test against related yeast proteins and human homologs
Multiple detection methods: Confirm findings using alternative techniques (mass spectrometry)
Epitope mapping: Determine precise binding regions on YMR265C
This multi-faceted validation approach follows best practices established in antibody research . Drawing from research on therapeutic antibodies, comprehensive validation prevents experimental artifacts and improves reproducibility. Researchers should document all validation steps in publications to support result interpretation.
Optimal dilution ranges for YMR265C antibody vary by application:
| Application | Recommended Dilution Range | Optimization Method |
|---|---|---|
| Western Blot | 1:500 - 1:5000 | Titration experiment |
| ELISA | 1:1000 - 1:10000 | Checkerboard titration |
| IHC/IF* | 1:100 - 1:500 | Serial dilution testing |
*Additional validation required for immunohistochemistry/immunofluorescence applications
Optimization should begin with the manufacturer's recommendations, followed by empirical testing for each specific protocol and sample type. This methodological approach is similar to what has been established in antibody-based experimental designs for therapeutic antibody development . Final dilution will depend on expression level of YMR265C in the specific yeast strain and experimental conditions.
Researchers can integrate YMR265C antibody experimental data with machine learning models for antibody-antigen binding prediction by:
Generating library-on-library screening data of YMR265C variants against the antibody

Validating computational predictions with experimental binding assays
This approach mirrors recent advances in antibody-antigen binding prediction research that demonstrated a 35% reduction in required antigen mutant variants and accelerated learning processes . Such methodologies are particularly valuable when predicting out-of-distribution interactions—cases where test antibodies and antigens differ from training data. By combining wet-lab experiments with computational predictions, researchers can more efficiently map the binding landscape of YMR265C and its antibody.
