Lyophilized from sterile PBS, pH 7.4 Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |
| Reconstitution | Please refer to the printed manual for detailed information. |
| Background | CNDP1; also known as carnosine dipeptidase 1; glutamate carboxypeptidase-like protein 2 (CPGL-2) or carnosinase 1 (CN1); is a member of the M20 metalloprotease family. The CNDP1 gene contains trinucleotide (CTG) repeat length polymorphism in the coding region; which has been demonstrated to be associated with susceptibility to developing diabetic nephropathy; for carnosine protection against the adverse effects of high glucose levels on renal cells. In humans; CNDP1 is secreted from the liver into the serum. In other mammals; including rodents; CNDP1 is expressed exclusively within the kidney and lacks a signal peptide. CNDP1 protein is a secreted homodimeric dipeptidase that specifically hydrolyzes L-carnosine (β-alanyl-L-histidine); and is identified as human carnosinase expressed in the brain. CNDP1 has been associated with diabetic nephropathy in Europeans and European Americans; but not African-Americans. It was identified and confirmed as a risk factor; were cross-sectional and mostly in patients with type 2 diabetes. The polymorphisms of CNDP1 can be excluded as a risk factor for nephropathy in type 1 diabetes. In addition; CNDP1 is also suggested to be implicated in the actions of neuroprotection and neurotransmiting. |
