Amyloid Beta (1-42) ELISA Kit (Rat/Mouse)


Rat/mouse amyloid beta (1-42) ELISA kit can be used for detecting quantitative concentrations of amyloid beta (Aβ, Abeta, beta-amyloid)(1-42) in rat and mouse EDTA plasma or serum samples. This assay has a minimum sensitivity detection limit of 0.05 pg/ml.


Amyloid beta (also known as beta-amyloid, Aβ and Abeta) is made up of peptides that range from 36-43 amino acids and these are important in Alzheimer’s disease because amyloid plaques have been discovered in the brains of Alzheimer patients. Senile plaques that have been identified consist of both Aβ40 and Aβ42, whereas the vascular amyloid predominately contains the shorter Aβ40. Also, due to its more hydrophobic nature Aβ42 is regarded as the more amyloidogenic form of the peptide. Many functions of amyloid beta have been found such as activation of kinase enzymes, regulation of cholesterol transport, functioning as a transcription factor, protection against oxidative stress and anti-microbial activity.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

The minimum sensitivity detection limit of beta-amyloid (Aβ, Abeta) using current rat/mouse amyloid beta (1-42) ELISA kit was approximately 0.05 pg/ml. The dynamic range for this assay is 1.56 – 100.0 pg/ml.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
