The y06P protein is a component of Enterobacteria phage T4 (Bacteriophage T4) with the UniProt accession number P39223. This protein plays a role in the phage lifecycle, making it an important target for studying bacteriophage biology and host-phage interactions. Researchers target this protein to investigate phage structural components, replication mechanisms, and potential applications in bacterial detection systems. The commercially available y06P Antibody is a polyclonal antibody raised in rabbits against recombinant Enterobacteria phage T4 y06P protein . This antibody serves as a valuable tool for detecting and studying the presence, distribution, and function of y06P protein in various experimental contexts.

What are the key specifications of commercially available y06P Antibody?

The y06P Antibody (Product Code: CSB-PA336545XA01EDZ) is a polyclonal, non-conjugated IgG antibody raised in rabbits. It is supplied in liquid form and should be stored at -20°C or -80°C to maintain stability and functionality, with repeated freeze-thaw cycles being avoided. The antibody is preserved in a specific buffer composition (0.03% Proclin 300, 50% Glycerol, 0.01M PBS, pH 7.4) and has undergone antigen affinity purification to ensure specificity . This high level of purification makes it suitable for sensitive applications requiring minimal background interference.

What validated applications has the y06P Antibody been tested for?

According to the manufacturer's specifications, the y06P Antibody has been validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blot (WB) applications . These validation tests confirm the antibody's ability to specifically recognize y06P protein in different experimental formats. While these are the validated applications, experienced researchers may adapt the antibody for use in additional techniques after conducting appropriate validation studies specific to their experimental systems.

How should researchers design experiments to verify y06P Antibody specificity?

Verifying antibody specificity is critical for research integrity. For y06P Antibody, researchers should:

• Positive Controls: Include purified recombinant y06P protein at known concentrations.
