zgc:158412 Antibody

What is zgc:158412 and why is it important in zebrafish research?

Zgc:158412 is a protein encoded by a zebrafish (Danio rerio) gene with the Entrez Gene ID 566090 and UniProt accession number A0PJS5 . This protein is part of the zebrafish genome collection (zgc) and serves as an important marker in developmental biology research. The antibody against zgc:158412 is particularly valuable for tracking protein expression patterns during zebrafish embryonic development. The importance of this antibody lies in its specificity to zebrafish cellular components, which allows researchers to visualize protein localization and expression timing during critical developmental stages. Understanding zgc:158412 expression contributes to broader knowledge of zebrafish embryogenesis and comparative vertebrate development studies .

What are the key technical specifications of the zgc:158412 antibody?

The zgc:158412 antibody is available as a polyclonal antibody derived from rabbit immunized with recombinant Danio rerio (zebrafish) zgc:158412 protein . The key technical specifications include:

These specifications provide researchers with essential information for determining the suitability of this antibody for specific experimental applications in zebrafish studies .

How does the recognition epitope of zgc:158412 antibody affect its application in developmental studies?

The recognition epitope of the zgc:158412 antibody is derived from the recombinant Danio rerio zgc:158412 protein used as an immunogen . The epitope specificity significantly impacts its utility in developmental studies in several ways. First, the polyclonal nature of this antibody means it recognizes multiple epitopes on the target protein, potentially increasing sensitivity but requiring careful validation to ensure specificity. Second, researchers must consider epitope accessibility during different developmental stages, as protein folding, post-translational modifications, or protein-protein interactions may mask the epitope in certain cellular contexts or developmental timepoints.

When designing developmental time-course experiments, researchers should verify that the epitope remains accessible throughout the developmental stages being studied. This verification can be accomplished through parallel experiments using alternative detection methods or through careful positive and negative controls. The antibody comes with positive control antigens (200μg) and negative control pre-immune serum (1ml) to facilitate proper experimental validation . Cross-reactivity testing with related zebrafish proteins should be performed to ensure the observed signals truly represent zgc:158412 expression patterns during development.

What are the optimized protocols for Western blotting using zgc:158412 antibody?

When performing Western blotting with zgc:158412 antibody, researchers should follow this optimized protocol:
