Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%

Review: I am using CSB-E11899h (human netrin-1 ELISA kit) for the first time. I have done various ELISA before, but the cusabio ELISA product has become my first choice product due to its sensitivity. I like to use this very much except there is an activation step for this netrin-1 protein. As soon as I activate the sample becomes coagulated. I haven\'t used any other Netrin-1 ELISA kit. So just facing this problem even in case of a fresh sample.

Target Background

(From Uniprot)
Netrins control guidance of CNS commissural axons and peripheral motor axons. Its association with either DCC or some UNC5 receptors will lead to axon attraction or repulsion, respectively. Binding to UNC5C might cause dissociation of UNC5C from polymerized TUBB3 in microtubules and thereby lead to increased microtubule dynamics and axon repulsion. Involved in dorsal root ganglion axon projection towards the spinal cord. It also serves as a survival factor via its association with its receptors which prevent the initiation of apoptosis. Involved in tumorigenesis by regulating apoptosis.
