Do not mix components from different kit lots or use reagents beyond the kit expiration date.
Allow all reagents to warm to room temperature for at least 30 minutes before opening.
Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
Unused wells must be kept desiccated at 4 C in the sealed bag provided.
Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
It is recommended that all samples and standards be assayed in duplicate or triplicate.

Gel pack with blue ice.

Plasma levels of PIIINP a marker of extracellular matrix metabolism activity have been linked to abdominal aortic aneurysm growth rate, but its relationship with thoracic aortic aneurysm (TAA) growth has never previously been studied. The PIIINP molecule is an indicator of both the synthesis and the degradation of type III collagen. Occasionally, the removal of PIIINP from the newly-synthesized type III collagen is not complete and the propeptide may remain attached to some of the molecules, known as type IIIpN-collagen. PIIINP is a degradation product of type IIIpN collagen. PIIINP has a molecular weight of 42 000 and contains three distinct domains: a triple-helical domain (Col 3) in the middle of the molecule, the Col 1-domain at the aminoterminal and Col 2-domain at the carboxyterminal end of the propeptide. PIIINP is cleared from the circulation by scavenger receptors in liver endothelial cells.
