Background of Ficolin-2
Ficolin-2, which was initially identified as L-ficolin, is a protein that in humans is encoded by the FCN2 gene. The product of this gene belongs to the ficolin family of proteins. This family is characterized by the presence of a leader peptide, a short N-terminal segment, followed by a collagen-like region, and a C-terminal fibrinogen-like domain. It is mapped to 9q34.3. This gene is predominantly expressed in the liver, and has been shown to have carbohydrate binding and opsonic activities. Serum concentration of ficolin-2 varies considerably in healthy individuals. FCN2 promoter polymorphisms were associated with marked changes in theficolin-2 serum concentration.

Question
Q: What is the optimal O.D. value for Ficolin-2 ELISA kit? I used your Ficolin-2 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 Ficolin-2 even though the O.D. values are not very high?
E. Chakrabarti
Verified customer
Asked: 2020-09-08
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. 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. 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 Ficolin-2 ELISA kit to have sensitivity of 20pg/ml, that means the minimum amount of Ficolin-2 that can be declared/interpreted as positive by the above standard is 20pg/ml.

Question
Q: Can Ficolin-2 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2019-12-08
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 valid for other sample types than we have tested: it means further investigation is a must. 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 assessd 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: if the enzyme conjugated Ficolin-2 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 Ficolin-2 antigen?
Verified Customer
Verified customer
Asked: 2019-12-02
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: how to thaw whole blood sample for Ficolin-2 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2018-05-21
Answer
A: do not freeze 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 Ficolin-2 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement Ficolin-2 using the EK1258 Human Ficolin-2 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2017-06-16
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 right after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples to limit protein degradation.
