The organization of the epithelium of the small intestine and colon into crypts is generally comparable. However, histologically there are two important differences between the two types of epithelia.The colonic epithelium has a flat epithelium surface and does not have villi. Regeneration occurs from units embedded within the crypts, each containing about 6–10 stem cells, while differentiated epithelial cells reside at the surface. Human colonic epithelium is linked to various human diseases and disorders such as Ulcerative Colitis and Colon Cancer, necessitating a better understanding of epithelial cell function and their role in disease-affected tissues. CAI’s colonic epithelial culture system provides a unique tool for the investigation of colon epithelial cell physiology and evaluation of therapeutic mediators for translational research.

The EGFR L861Q Reference Standard is genomic DNA derived from a highly characterized homozygous diploid HCT116 cell line, genetically modified with advanced genome editing technology to include the mutation L861Q in EGFR on both chromosomes. The variant allele frequency (VAF) is 100%, and can be diluted using the corresponding wild-type standard to reach lower VAF. This reference standard can be used to assess the performance of your NGS, sanger sequencing and qPCR assay, including the limit of detection, accuracy, and precision.
