Our lab has been using the aptamer for several experiments focused on phenylalanine detectionExcellentThe specificity is excellent, showing minimal cross-reactivity with other amino acids, which was crucial for our assays. The aptamer consistently binds to phenylalanine with high affinity. We also appreciated the stability of the product during multiple rounds of testing. Overall, it's a reliable tool that has enhanced the accuracy of our experimental outcomes.
Great sensitivity and accuracy in detectionExcellentThe sensitivity of this aptamer is impressive, particularly when quantifying low levels of phenylalanine in biological samples. We've run numerous ELISA-like assays, and the results have been very consistent. The binding kinetics are fast, which makes it convenient when time is a factor. The aptamer's performance has proven superior to some traditional antibodies we've used in the past.
Consistent performance across various assaysExcellentI've used this aptamer for phenylalanine detection in both liquid chromatography and colorimetric assays. In both methods, it has provided consistent and reproducible results. What stands out is the aptamer's low non-specific binding, leading to clear and distinct signals. The lyophilized format made storage easy, and reconstitution was simple without any loss in performance.
We are currently developing a biosensor, and the aptame has been a key componentExcellentThe aptamer's specificity and strong affinity for phenylalanine have been crucial for accurate signal detection. Even after multiple binding events, the aptamer maintained its performance. It integrates seamlessly into our device, demonstrating great stability under different pH conditions.
Stable and reproducible for long-term studiesExcellentWe've been working with this aptamer for over six months, and it has delivered stable results throughout. Even with prolonged storage, there's been no noticeable decrease in its binding efficiency. This reproducibility has been critical for our longitudinal studies on phenylalanine metabolism. It's a cost-effective alternative to antibodies while delivering comparable, if not better, results.
