YPR130C Antibody

What is YPR130C and what cellular functions does it participate in?

YPR130C is a protein expressed in Saccharomyces cerevisiae (Baker's yeast). While the search results don't provide detailed information about the specific functions of YPR130C, it is a target for research in yeast molecular biology. Understanding the function of YPR130C requires consulting yeast genome databases and functional studies in the literature.

When designing experiments targeting this protein, researchers should first review the current literature on YPR130C function, localization, and interaction partners to establish appropriate experimental conditions and controls that reflect the protein's native environment and activity.

What applications is the YPR130C antibody validated for?

The YPR130C antibody has been validated for the following applications:

• ELISA (Enzyme-Linked Immunosorbent Assay)

• Western Blot (WB)

When implementing these applications, researchers should first perform optimization steps to determine the ideal antibody concentration, incubation conditions, and detection methods for their specific experimental system. For Western blots, begin with a dilution series (e.g., 1:500, 1:1000, 1:2000) to identify the optimal concentration that maximizes specific signal while minimizing background.

How should YPR130C antibody be stored to maintain its activity?

For optimal preservation of antibody activity:

• Upon receipt, store at -20°C or -80°C

• Avoid repeated freeze-thaw cycles that can cause protein denaturation and loss of binding capacity

• The antibody is supplied in a liquid form containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative

For long-term storage beyond 6 months, aliquoting the antibody into smaller volumes before freezing is recommended to prevent repeated freeze-thaw cycles. Working aliquots can be stored at 4°C for up to 2 weeks for ongoing experiments.

What is the species reactivity of YPR130C antibody?

The YPR130C antibody specifically reacts with Saccharomyces cerevisiae (strain ATCC 204508/S288c), commonly known as Baker's yeast . When planning cross-reactivity studies, researchers should note that antibodies raised against yeast proteins may show limited cross-reactivity with orthologous proteins from other fungal species depending on sequence conservation.

How can I optimize Western blot conditions for YPR130C detection in yeast lysates?

Optimization of Western blot conditions requires systematic adjustment of multiple parameters:

For yeast samples specifically, include a rigorous cell wall disruption step in your protein extraction protocol (such as glass bead lysis or enzymatic treatment with zymolyase) to ensure efficient release of intracellular proteins. When detecting YPR130C, consider using PVDF membranes rather than nitrocellulose for potentially better protein retention and signal strength.

How can I distinguish between specific and non-specific signals when using YPR130C antibody?

Distinguishing between specific and non-specific signals requires multiple validation approaches:

• Positive and negative controls: Include samples from wild-type and YPR130C knockout strains

• Peptide competition assay: Pre-incubate the antibody with excess purified YPR130C protein or immunogenic peptide to block specific binding sites

• Secondary antibody only control: Omit primary antibody to identify non-specific secondary antibody binding

• Size verification: Confirm that the detected band matches the expected molecular weight of YPR130C

• Alternative detection methods: Validate results using an independent method (e.g., mass spectrometry)

In cases where background remains problematic, consider implementing a more stringent washing protocol or using alternative blocking reagents such as fish gelatin or commercial blocking solutions designed for yeast applications.

How can I use YPR130C antibody for co-immunoprecipitation experiments?

When designing co-immunoprecipitation (Co-IP) experiments with YPR130C antibody:

• Buffer optimization: Test multiple lysis buffers to identify conditions that preserve protein-protein interactions while efficiently extracting YPR130C

  • Start with a gentle buffer (e.g., 50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1% NP-40, protease inhibitors)

  • Adjust salt concentration (100-300 mM) to balance extraction efficiency and interaction preservation

• Antibody immobilization: Covalently couple the antibody to protein A/G beads using crosslinking reagents (e.g., DMP or BS3) to prevent antibody co-elution with the target protein

• Controls:

  • Input control: 5-10% of lysate before immunoprecipitation

  • Negative control: Non-specific IgG from the same species

  • Bead-only control: Beads without antibody

  • Reverse Co-IP: Use antibodies against suspected interaction partners

• Elution conditions: Test multiple elution strategies (competitive elution with peptide, pH elution, or direct boiling in SDS sample buffer) to identify the most efficient method

Analysis of Co-IP results should include normalization to input controls and quantification of enrichment relative to negative controls using densitometry.

How should I design experiments to control for the polyclonal nature of YPR130C antibody?

The polyclonal nature of this antibody introduces specific considerations for experimental design:

• Lot-to-lot variation: Maintain records of antibody lot numbers and perform validation with each new lot

• Epitope diversity: The antibody recognizes multiple epitopes, which may affect results in applications where epitope accessibility varies

• Cross-reactivity risk: Include additional controls to confirm specificity:

  • Pre-adsorption controls with purified antigen

  • Parallel experiments with epitope-tagged YPR130C and tag-specific antibodies

  • Genetic knockouts or knockdowns of YPR130C as negative controls

When publishing results, include detailed information about antibody validation steps, lot numbers, and specific experimental conditions to facilitate reproducibility by other researchers.

What considerations should be made when using YPR130C antibody for protein localization studies?

For immunofluorescence or immunohistochemistry applications:

• Fixation optimization: Test multiple fixation methods:

  • Paraformaldehyde (2-4%) for structural preservation

  • Methanol for increased permeabilization

  • Hybrid protocols combining aldehyde and alcohol fixation

• Epitope retrieval: Yeast cell wall can impede antibody access; consider:

  • Enzymatic digestion (zymolyase, lyticase)

  • Heat-induced epitope retrieval in citrate buffer

  • Permeabilization with detergents (0.1-0.5% Triton X-100 or saponin)

• Signal amplification: For low-abundance proteins, implement:

  • Tyramide signal amplification (TSA)

  • Secondary antibody with higher fluorophore conjugation ratios

  • Biotin-streptavidin amplification systems

• Controls for specificity:

  • Peptide competition controls

  • Genetic controls (knockout/knockdown)

  • Secondary antibody-only controls

  • Comparative localization with tagged version of YPR130C

How can I quantitatively analyze YPR130C expression levels in different yeast strains or conditions?

For quantitative analysis of YPR130C expression:

For each method, implement technical replicates (n≥3) and biological replicates (n≥3) to ensure statistical validity. When comparing expression across conditions, use appropriate statistical tests (t-test, ANOVA) with correction for multiple comparisons when applicable.

What are common issues in Western blot detection of YPR130C and how can they be resolved?

When troubleshooting Western blot issues with YPR130C detection, implement a systematic approach that modifies one variable at a time while keeping others constant. Document all protocol modifications and their effects on signal quality to build an optimized protocol.
