EHT1 Antibody

What is EHT1 Antibody and what are its target specifics?

EHT1 Antibody (product code CSB-PA336431ZA01SVG) is a polyclonal antibody raised in rabbits that specifically recognizes the EHT1 protein from Saccharomyces cerevisiae (Baker's yeast). It is a non-conjugated antibody in liquid form that has been purified using antigen affinity methods. This antibody is developed for research purposes only and should not be used in diagnostic or therapeutic procedures .

What are the recommended applications for EHT1 Antibody?

EHT1 Antibody has been tested and validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blot (WB) applications. These applications allow for the detection and quantification of EHT1 protein in experimental samples. The antibody's specificity for Saccharomyces cerevisiae makes it particularly valuable for yeast-based research systems .

What are the optimal storage and handling conditions?

For optimal stability and performance, EHT1 Antibody should be stored at either -20°C or -80°C upon receipt. It's crucial to avoid repeated freeze-thaw cycles as these can compromise antibody activity and specificity. The antibody is supplied in a storage buffer containing 0.03% Proclin 300 as a preservative, 50% Glycerol, and 0.01M PBS at pH 7.4, which helps maintain stability during storage .

How should I validate EHT1 Antibody for my specific research application?

Proper validation of EHT1 Antibody requires a multi-step approach:

• Subcellular localization verification: Confirm that staining patterns match the expected localization of EHT1 in yeast cells.

• Quantitative titration: Perform serial dilutions to determine optimal antibody concentration that maximizes specific signal while minimizing background.

• Orthogonal validation: Use independent methods such as mass spectrometry to confirm target protein identification.

• Genetic validation: When possible, use EHT1 knockout/knockdown samples as negative controls.

• Reproducibility testing: Verify consistent performance across different experiments and antibody lots .

How can I distinguish between specific and non-specific binding?

Distinguishing specific from non-specific binding requires systematic controls:

• Negative controls: Include samples known to lack EHT1 expression.

• Competitive binding assays: Pre-incubate the antibody with purified EHT1 protein to block specific binding sites.

• Multiple epitope targeting: Compare results with alternative antibodies targeting different regions of EHT1.

• Signal pattern analysis: Specific binding typically shows consistent patterns across replicates, while non-specific binding appears more random.

• Orthogonal methods validation: Confirm findings using techniques that don't rely on antibody recognition .

What factors might affect EHT1 Antibody specificity in experimental conditions?

Several factors can influence antibody specificity:

• Antibody concentration: Excessive concentrations often lead to increased non-specific binding.

• Sample preparation: Fixation methods, protein denaturation, and epitope masking can affect antibody recognition.

• Incubation conditions: Temperature and duration influence binding equilibrium.

• Cross-reactive epitopes: Structurally similar proteins may share epitopes recognized by the antibody .

How should I design experiments to investigate EHT1 function in yeast?

When designing experiments to study EHT1 function:
