PER66 Antibody

What is the PER66 Antibody and what systems is it best suited for?

PER66 Antibody is a polyclonal antibody raised against Arabidopsis thaliana (Mouse-ear cress) antigens, designed specifically for research applications in plant biology . This antibody targets the PER66 protein, also known by the gene name PER66, and is primarily used in plant research systems focused on Arabidopsis thaliana as the model organism. The antibody is typically made-to-order with a lead time of 14-16 weeks, requiring researchers to plan experiments accordingly . It's important to note that this antibody is intended strictly for research purposes and not for diagnostic or therapeutic applications.

What are the recommended storage conditions for PER66 Antibody to maintain functionality?

For optimal preservation of antibody functionality, PER66 Antibody should be stored at -20°C or -80°C upon receipt . Repeated freeze-thaw cycles should be strictly avoided as they can significantly compromise antibody performance through protein denaturation and aggregation. When designing experiments involving this antibody, researchers should incorporate proper sample handling protocols, including aliquoting the antibody upon receipt to minimize freeze-thaw cycles. This storage approach aligns with standard experimental design considerations that emphasize controlling extraneous variables that might affect experimental outcomes .

How should researchers validate PER66 Antibody specificity in Arabidopsis studies?

When validating antibody specificity, researchers should implement a systematic experimental design that includes both positive and negative controls. For PER66 Antibody, this typically involves:

• Western blot analysis: Compare wild-type Arabidopsis samples with per66 knockout/knockdown lines

• Immunohistochemistry verification: Perform parallel staining with secondary antibody alone to rule out non-specific binding

• Pre-absorption controls: Pre-incubate the antibody with purified antigen before immunostaining

• Cross-reactivity testing: Test the antibody against related plant species to establish specificity

This validation approach follows proper experimental design principles by incorporating both control groups and experimental groups, ensuring that any observed effects are attributable to the specific antibody-antigen interaction rather than to artifacts or cross-reactivity .

What are the recommended starting dilutions for different applications of PER66 Antibody?

While specific dilution recommendations for PER66 Antibody aren't detailed in the available data , researchers should establish optimal working dilutions through systematic titration experiments. This involves:
