Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Rat Activin A 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.

7 Customer Q&As for Rat Activin A ELISA Kit PicoKine™
Question
Q: is it okay to use citrate plasma as samples in Rat Activin A Picokine® ELISA Kit (Catalog # EK0303)?
C. Lewis
Verified customer
Asked: 2020-01-30
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of Activin A causing disruption of its protein structure. Activin A may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the Activin A ELISA, treating samples with a number of anticoagulants and decided that heparin or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Do you sell the wells/strips from EK0303 Elisa kit separately without the buffers?
Verified customer
Asked: 2020-01-14
Answer
We sell the complete kit. The only thing that gets sold separately if needed are the standards. We don't really disintegrate our kits and sell as it requires additional time and effort to do that. Also, the components to be saved are of no use to us as they are from particular lot numbers.

Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2018-06-08
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found in the product insert. Components in lysate and lysis buffer may affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: how many samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2016-09-24
Answer
A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may depends upon the kit used so please refer to each datasheet for details.

Question
Q: What is the optimal O.D. value for Activin A ELISA kit? I used your Activin A ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. can I consider these samples contain Activin A even though the O.D. values are not very high?
R. Wu
Verified customer
Asked: 2016-01-27
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. regarding your protocol, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. typically, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by converting cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this Activin A ELISA kit to have sensitivity of 12pg/ml, that means the minimum amount of Activin A that can be declared/interpreted as positive by the above standard is 12pg/ml.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring Activin A using the EK0303 Rat Activin A Picokine® ELISA Kit?
L. Anand
Verified customer
Asked: 2015-03-31
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples in order to prevent protein degradation.
