Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Cardiotrophin-1 / CTF1 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.

Question
Q: Can Cardiotrophin-1 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-10-31
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 check 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.

Question
Q: can I use citrate plasma as samples in Human Cardiotrophin-1 Picokine® ELISA Kit (Catalog # EK0563)?
G. Wright
Verified customer
Asked: 2020-10-10
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of Cardiotrophin-1 causing disruption of its protein structure. Cardiotrophin-1 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes required for detection and block the antigen antibody reaction. We have tested the Cardiotrophin-1 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
Q: if the enzyme conjugated Cardiotrophin-1 antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the Cardiotrophin-1 antigen?
P. Green
Verified customer
Asked: 2020-03-05
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.

Question
Q: What is the optimal O.D. value for Cardiotrophin-1 ELISA kit? I performed your Cardiotrophin-1 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 Cardiotrophin-1 even though the O.D. values are not very high?
H. Hernandez
Verified customer
Asked: 2019-12-27
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. an important assessment 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 relation 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 changeing 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 Cardiotrophin-1 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Cardiotrophin-1 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
In the EK0563 manual provided it is stated to store all reagents at -20°C. However, on the label of the reagents/plates/standards it is stated to store them at 4°C (as we did). Could this difference in storage temperature be of influence on cardiotrophin that is measured in the samples?
Verified customer
Asked: 2019-04-09
Answer
There should not be any storage condition on the label of the reagents/plates/standards for the Human Cardiotrophin-1 / CTF1 ELISA Kit PicoKine™ (EK0563). We only state the storage condition on the label sticking outside the kit box and in the manual. "Store at 4°C for 6 months, at -20°C for 12 months." So, since you are storing the product components at these temperatures, there should not be an influence on the performance.

Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2019-02-09
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 may affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of Cardiotrophin-1 in Human serum? I am trying to measure a multiple analytes and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2018-03-15
Answer
A: without knowing the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the Cardiotrophin-1 ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service

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 required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.
