Intra Assay Consistency & Inter Assay Consistency

We measured random samples of Mouse FGF21 ELISA Kit PicoKine™ within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement FGF-21 using the EK1379 Mouse FGF-21 Picokine® ELISA Kit?

D. Varma

Verified customer

Asked: 2018-10-26


A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples to prevent protein degradation.

We have a customer who wants to purchase your Human PROS1 PicoKine ELISA Kit EK1739-96WELLS because they are interested in the human PROS1. However, at a later time point maybe also PROS1 in mice. Do you have any data if the kit might work with mice? Normally you say if the sequence if the sequences are 90%+ identical, there is a high chance of cross-reactivity

Our lab technicians didn't detect PROS1 in serum from healthy mice. Best Regards,

I only have 20 µL of plasma sample. Can I dilute the sample to 100 µL for this assay?

Verified Customer

Verified customer

Asked: 2014-08-14


Yes if the sample is mouse plasma. Note that we do not recommend this dilution for human plasma because its FGF21 level is lower than that in mouse plasma.
