Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Eotaxin / CCL11 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.

8 Customer Q&As for Human Eotaxin / CCL11 ELISA Kit PicoKine™
Question
Q: What is the optimal O.D. value for CCL11 ELISA kit? I used your CCL11 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 CCL11 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2019-12-08
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. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the example mentioned, 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. normally, 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 CCL11 ELISA kit to have sensitivity of 2pg/ml, that means the minimum amount of CCL11 that can be declared/interpreted as positive by the above standard is 2pg/ml.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
C. Lewis
Verified customer
Asked: 2019-10-04
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included in the product insert. Components in lysate and lysis buffer can have an affect on immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: Can CCL11 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2018-09-15
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not suitable for other sample types than we have tested: it means further investigation is needed. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been evaluated by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please view the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: is it okay to use heparin plasma as samples in Human CCL11 Picokine® ELISA Kit (Catalog # EK0329)?
E. Banerjee
Verified customer
Asked: 2017-04-09
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of CCL11 causing disruption of its protein structure. CCL11 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 CCL11 ELISA, treating samples with a number of anticoagulants and decided that citrate or EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: if the enzyme conjugated CCL11 antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the CCL11 antigen?
Verified Customer
Verified customer
Asked: 2016-01-04
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.
