Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.

WA1 is a mouse IgG1 monoclonal antibody derived from the fusion of SP2 mouse myeloma cells with splenocytes from a BALB/c mouse immunized with human p21 protein.
An epitope within the carboxy-terminal region of p21/WAF1.
p21/WAF1, also known as cip1 and cyclin-dependent kinase interacting protein 1, is a 21kD protein that belongs to the CDI family of cyclin-dependent kinase inhibitors. In humans p21/WAF1 is encoded by the CDKN1A gene, the transcription of which is regulated by P53, for example in the case of DNA damage. The p21/WAF1 protein exists within the nucleus as a complex with cyclin, cyclin-dependent kinase (cdk) and proliferating cell nuclear antigen (PCNA). It functions as a potent inhibitor of cyclin-dependent kinases and plays a critical role in regulating cell growth and the cellular response to DNA damage.
CDKN1A / WAF1 / p21 is a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-CDK2 or -CDK4 complexes, and thus functions as a regulator of cell cycle progression at G1. The expression of this gene is tightly controlled by the tumor suppressor protein p53, through which this protein mediates the p53-dependent cell cycle G1 phase arrest in response to a variety of stress stimuli.
