While detailed functional information is limited in current literature, this protein is part of the plant's proteome and studying it may provide insights into plant development, stress responses, or signaling pathways. The LCR53 antibody enables detection and characterization of this protein in various experimental contexts, advancing our understanding of plant biology .

What detection methods are validated for LCR53 Antibody?

The LCR53 Antibody (CSB-PA306001XA01DOA) has been validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blot (WB) applications. These techniques allow for both qualitative and quantitative analysis of LCR53 protein in plant tissue extracts. When designing experiments, researchers should consider that each application requires specific optimization parameters including antibody dilution, incubation time, and detection systems .

What are the critical storage and handling recommendations for preserving LCR53 Antibody activity?

For optimal antibody performance, store LCR53 Antibody at -20°C or -80°C immediately upon receipt. The antibody is supplied in liquid form with a preservation buffer containing 0.03% Proclin 300, 50% Glycerol, and 0.01M PBS at pH 7.4. Critically, repeated freeze-thaw cycles should be avoided as they can significantly compromise antibody functionality and specificity. Consider aliquoting the antibody upon first thaw to minimize future freeze-thaw events .

How should researchers determine optimal working dilutions for LCR53 Antibody?

Determining the optimal working dilution for LCR53 Antibody requires systematic titration experiments:

• Prepare a dilution series (e.g., 1:500, 1:1000, 1:2000, 1:5000) of the antibody

• Test each dilution against positive control samples (Arabidopsis thaliana tissues known to express LCR53)

• Evaluate signal-to-noise ratio, specificity, and background for each dilution

• Select the dilution that provides optimal specific signal with minimal background

This optimization is essential as suboptimal antibody concentrations can result in either excessive background (too concentrated) or insufficient signal (too dilute), both compromising experimental interpretation .

What essential controls should be incorporated in LCR53 Antibody experiments?

When designing experiments using LCR53 Antibody, include these critical controls:

• Positive control: Wild-type Arabidopsis thaliana tissue sample known to express LCR53

• Negative control: Either LCR53 knockout/knockdown lines or tissues where LCR53 is not expressed

• Technical control: Primary antibody omission to assess secondary antibody specificity

• Loading control: Detection of a constitutively expressed plant protein (e.g., actin, tubulin) for normalization

These controls help validate experimental results and facilitate troubleshooting of technical issues that may arise during antibody-based detection .

What are the recommended sample preparation methods for optimal LCR53 detection in plant tissues?

Optimal sample preparation is crucial for successful detection of LCR53 in plant tissues:

For all tissue types, maintain sample integrity by flash-freezing in liquid nitrogen immediately after collection and performing all extraction steps at 4°C with appropriate protease inhibitors to prevent protein degradation .

How can researchers address weak or absent signal when using LCR53 Antibody in Western blots?

When encountering weak or no signal with LCR53 Antibody in Western blots, implement this systematic troubleshooting approach:

• Verify protein extraction efficiency using a total protein stain (Ponceau S or Coomassie)

• Increase antibody concentration incrementally (e.g., from 1:1000 to 1:500)

• Extend primary antibody incubation time (overnight at 4°C)

• Optimize blocking conditions (test different blocking agents: 5% BSA vs. 5% non-fat milk)

• Enhance detection sensitivity by using a more sensitive chemiluminescent substrate

• Assess protein loading (increase if expression levels are low)

• Evaluate transfer efficiency, particularly for proteins with challenging molecular weights

Documenting each troubleshooting step will help establish optimal protocols for consistent LCR53 detection .

What strategies can mitigate non-specific binding when using LCR53 Antibody?

Non-specific binding can compromise experimental interpretation. Address this issue through:

• Optimize blocking: Increase blocking agent concentration (5-10% BSA or non-fat milk) or extend blocking time

• Modify washing conditions: Increase wash buffer stringency with higher detergent concentration (0.1-0.3% Tween-20)

• Pre-absorb antibody: Incubate diluted antibody with negative control lysate before application to experimental samples

• Adjust antibody dilution: Higher dilutions may reduce non-specific interactions

• Evaluate secondary antibody: Test alternative secondary antibodies or increase dilution

These approaches should be systematically tested to determine which provides optimal specific signal while minimizing background .

How can researchers validate LCR53 Antibody specificity for their particular experimental system?

Rigorous antibody validation is essential for reliable research outcomes. For LCR53 Antibody, implement these validation strategies:

• Genetic approach: Compare antibody reactivity between wild-type and LCR53 knockout/knockdown Arabidopsis lines
