Each All-in-One™ qPCR Primer is experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted gene. A cDNA Pool, containing reverse transcript products of 8 different human tissue total RNA(Liver, Testis,Muscle,Thyroid,Brain,Spleen,Stomach,Small Intestine)),was used as the qPCR validation template. qPCR was performed using 0.2 µM primer with 2XAll-in-One™ qPCR Mix (Catalog#: QP001,QP002,QP004,QP005). Reactions were incubated for 10min. at 95°C, followed by 40 cycles of 95°C for 10 sec.; 60°C, 20 sec. and 72°C, 15sec. using Bio-Rad iQ5™ Instrument. At the end of the last cycle, temperature was increased from 72 to 95°C to produce a melting curve. Panel A: Validated Result for Amplification Curve; Panel B: Validated Result for Melting Curve. |

Summary
The protein encoded by this gene is identical to adenosine deaminase complexing protein-2, and to the T-cell activation antigen CD26. It is an intrinsic membrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides. [provided by RefSeq].
