Background of EGF
Epidermal growth factor (EGF) is a growth factor that plays an important role in the regulation of cell growth, proliferation and differentiation by binding to its receptor EGFR. EGF locus is mapped to 4q21-4qter. Human EGF is a 6045-Da protein with 53 amino acid residues and three intramolecular disulfide bones. EGF results in cellular proliferation, differentiation, and survival while plays a physiological role in the maintenance of oro-esophageal and gastric tissue integrity.

Recommended Sample Dilution Ratios
According to our internal validation assays using this ELISA kit, to detect EGF, Dilution ratio of 1:1, concentration in serum and plasma is less than the lowest standard, 7.8 pg/ml..
Some articles we found to cite concentrations of EGF in samples: 18972736 (Pubmed IDs).
Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Rat EGF 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 Rat EGF ELISA Kit PicoKine®
Question
Q: can you recommend the dilution ratio of serum samples for detection of EGF in Rat serum? I am trying to measure a few parameters and it requires 100ul of diluted samples for each well. We have low serum volumes so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2019-12-31
Answer
A: having little idea about 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 EGF 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
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
S. Mitchell
Verified customer
Asked: 2019-05-27
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 change immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: can I use citrate plasma as samples in Rat EGF Picokine® ELISA Kit (Catalog # EK0954)?
Verified Customer
Verified customer
Asked: 2018-07-17
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of EGF causing degradation of its protein structure. EGF 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 EGF ELISA, treating samples with various 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 EGF 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 EGF antigen?
Verified Customer
Verified customer
Asked: 2017-10-21
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: which procedure should I follow in order to thaw whole blood sample for EGF ELISA after freezing?
Verified Customer
Verified customer
Asked: 2017-05-08
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 EGF for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer

Asked: 2016-01-14
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.
