IHC or immunohistochemistry anti complement C3 antibody generally involves the process of selectively imaging antigens such as mostly proteins in the animal cells as well as tissues section. By exploring the process of how antibodies generally tend to bind with antigen we can be able to understand its mechanism. This process is widely used to identify as well as diagnose abnormal cells such as sarcoma cells or cells those are extensively available at cancerous tumors. This process is also widely used in basic research to understand the distribution and localizations of differently expressed proteins in different parts of biological tissues.
