Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Fractalkine/CX3CL1 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.

6 Customer Q&As for Human Fractalkine/CX3CL1 ELISA Kit PicoKine™
Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2020-08-12
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 can impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2020-08-09
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification CX3CL1 using the EK0356 Human CX3CL1 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-02-09
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may alter 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 repeat freeze-thaw cycles with the stored samples in order to prevent protein degradation.

Question
Q: can I use citrate plasma as samples in Human CX3CL1 Picokine® ELISA Kit (Catalog # EK0356)?
Verified Customer
Verified customer
Asked: 2018-10-13
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of CX3CL1 causing degradation of its protein structure. CX3CL1 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes a must for detection and block the antigen antibody reaction. We have tested the CX3CL1 ELISA, treating samples with different 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
Q: What is the optimal O.D. value for CX3CL1 ELISA kit? I used your CX3CL1 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 CX3CL1 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-09-19
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. a point of focus should be is whether your sample O.D. values are statistically significantly higher than your blank values. regarding your assay, 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 proportion 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 CX3CL1 ELISA kit to have sensitivity of 50pg/ml, that means the minimum amount of CX3CL1 that can be declared/interpreted as positive by the above standard is 50pg/ml.

Question
Q: how to thaw whole blood sample for CX3CL1 ELISA after freezing?
M. White
Verified customer
Asked: 2016-05-28
Answer
A: we do not recommend freezing and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test CX3CL1 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.
