Background of MFG-E8
MFGE8 (Milk Fat Globule-Egf Factor 8), also called as Lactadherin or SED1, is a protein which in humans is encoded by the MFGE8 gene. Mfge8 is secreted protein found in vertebrates, including mammals as well as birds. By fluorescence in situ hybridization, the MFGE8 gene was mapped to chromosome 15q25. MFGE8 is a factor that links apoptotic cells to phagocytes. It specifically bound to apoptotic cells by recognizing aminophospholipids such as phosphatidylserine. MFGE8, when engaged by phospholipids, bound to cells via its RGD motif. It bound particularly strongly to cells expressing alpha-V-beta-3 integrin. It showed that Mfge8 was expressed in intestinal lamina propria macrophages in mice. Using a wound-healing assay, they showed that Mfge8 promoted migration of intestinal epithelial cells through a PKC-epsilon (PRKCE)-dependent mechanism.

Question
Q: What is the optimal O.D. value for MFG-E8 ELISA kit? I performed your MFG-E8 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. is it safe to say these samples contain MFG-E8 even though the O.D. values are not very high?
C. Taylor
Verified customer
Asked: 2020-08-15
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. considering 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 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 MFG-E8 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of MFG-E8 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: which procedure should I follow in order to thaw whole blood sample for MFG-E8 ELISA after freezing?
B. Zhou
Verified customer
Asked: 2019-05-15
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 MFG-E8 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2019-01-21
Answer
A: in 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 may affect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: is it okay to use citrate plasma as samples in Human MFG-E8 Picokine® ELISA Kit (Catalog # EK1201)?
Verified Customer
Verified customer
Asked: 2018-07-21
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of MFG-E8 causing disruption of its protein structure. MFG-E8 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 MFG-E8 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: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis MFG-E8 using the EK1201 Human MFG-E8 Picokine® ELISA Kit?
S. Wright
Verified customer
Asked: 2018-05-10
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 immediately after collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples in order to prevent protein degradation.
