Squamous cell carcinoma antigen 1 is a very important segment of the serpin family of specific proteins that acts as inhibitor of serine proteas family. This was initially marked for squamous cells carcinoma of the cervix area, now this squamous cell carcinoma antigen 1 is said to be associated with various cancerous epithelial tissues as well as endodermal tissues. Thus, on an overall basis, this helps in limiting damage of cells that are caused by lysosomal injuries. This also results in an association with DNA repairing, oxidation process and mitochondrial apoptosis. Predominantly located in the cytosol, squamous cell carcinoma antigen 1 can at times be released into certain extracellular environment.

Specific aspects of squamous cell carcinoma antigen 1:

As per tests, squamous cell carcinoma antigen 1 is specifically used for detecting of carcinoma. In case of usage, there are no such changes in in vitro  growth rate of HNSCC cells. A loss in expression of squamous cell carcinoma antigen 1 can result in accumulation of certain malignant cancerous issues. With passing time, tests conducted with help of Human squamous cell carcinoma antigen 1 (SCCAg1)ELISA Kit, have resulted in helping of gaining specific knowledge in regards to knowledge as marker for tumor and show the metastasis condition of cancerous tissues.
