KCNN4 mRNA is present in human colonic epithelial cells. Reverse transcription of total RNA from colonic crypts (HCC) performed in the presence (+) and absence (−) of Superscript and amplified using specific primers for human KCNN4. A human placental cDNA library (PL) amplified with KCNN4 primers acted as a positive control. DNA molecular weight ladder is shown on the far left of the gel.
