What applications are At4g18260 Antibodies most commonly used for?

At4g18260 Antibodies are primarily used in the following research applications:

When designing experiments, researchers should validate antibody specificity through knockout/knockdown controls, particularly given the similar sequences among cytochrome b561 family members in Arabidopsis (including At5g48750, At4g17280, At5g47530, and At5g54830) .

How should At4g18260 Antibody be stored and handled to maintain optimal activity?

For optimal activity maintenance, follow these methodological guidelines:

• Storage temperature: Store at 2-8°C for short-term (1-2 weeks) and -20°C for long-term storage

• Avoid repeated freeze-thaw cycles; aliquot upon first thaw

• Include carriers (e.g., BSA at 0.1%) for dilute solutions to prevent adsorption to tube surfaces

• Use sterile techniques when handling to prevent microbial contamination

• Document lot numbers and validation tests to track performance consistency
