Background of IGF-II/IGF2
Insulin-like growth factor II is also known as somatomedin A. IGF-2 is a member of the insulin family of polypeptide growth factors that is involved in development and growth. It is paternally expressed in the fetus and placenta. IGF-II is a mitogen for many cell types and an important modulator of muscle growth and differentiation. IGF-II gene is prevalently expressed during prenatal development and its gene activity is regulated by genomic imprinting, in that the allele inherited from the father is active and the allele inherited from the mother is inactive in most normal tissues. IGF-II appears to be induced by placental lactogen during prenatal development. It is a mediator of prolactin-induced alveologenesis; prolactin, IGF-2, and cyclin D1, all of which are overexpressed in breast cancers, are components of a developmental pathway in the mammary gland.

Question
Q: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
P. Liu
Verified customer
Asked: 2020-12-07
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are present in the product insert. Components in lysate and lysis buffer can affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: how can I thaw whole blood sample for IGF-II ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-06-16
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 IGF-II for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: if the enzyme conjugated IGF-II 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 IGF-II antigen?
S. Scott
Verified customer
Asked: 2019-11-15
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: can I use citrate plasma as samples in Mouse IGF-II Picokine® ELISA Kit (Catalog # EK0381)?
W. Liu
Verified customer
Asked: 2019-11-07
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of IGF-II causing disruption of its protein structure. IGF-II 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 IGF-II 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.

B. Mangal
Verified customer
Asked: 2019-09-23
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.

Question
Is EK0381 suitable for use with cerebrospinal fluid?
Verified Customer
Verified customer
Asked: 2019-09-15
Answer
Unfortunately, we haven't tested the Mouse IGF-2 ELISA Kit PicoKine™ (EK0381) on cerebrospinal fluid. We are uncertain if the kits are able to work on cerebrospinal fluid. Please run a pilot test if you want to try. In theory, if the expression level of the targets protein in the cerebrospinal fluid falls in the assay range of the kits, the kits are able to detect the protein in the sample.

Question
Q: What is the optimal O.D. value for IGF-II ELISA kit? I used your IGF-II 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 IGF-II even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2019-06-14
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. 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 IGF-II ELISA kit to have sensitivity of 5pg/ml, that means the minimum amount of IGF-II that can be declared/interpreted as positive by the above standard is 5pg/ml.

Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement IGF-II using the EK0381 Mouse IGF-II Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2014-12-17
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may alter the stabilityof samples. It is recommend to assay sample on-stat collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples in order to prevent protein degradation.
