Background of MAG/Siglec-4a

Myelin-associated glycoprotein (MAG, Siglec-4) is a cell membrane glycoprotein that is a member of the SIGLEC family of proteins and is a functional ligand of the NoGo-66 receptor (NgR). This gene is mapped to 19q13.12. The protein encoded by this gene is a type I membrane protein and member of the immunoglobulin superfamily. It is thought to be involved in the process of myelination. It is a lectin that binds to sialylated glycoconjugates and mediates certain myelin-neuron cell-cell interactions. Three alternatively spliced transcripts encoding different isoforms have been described for this gene.

8 Customer Q&As for Human MAG ELISA Kit PicoKine®

Question

Q: if the enzyme conjugated MAG 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 MAG antigen?

Verified Customer

Verified customer

Asked: 2020-05-20

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 are cell lysates prepared for use in Picokine® ELISA kits?

K. Rodriguez

Verified customer

Asked: 2020-04-29

Answer

A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found 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: What is the optimal O.D. value for MAG ELISA kit? I used your MAG 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 MAG even though the O.D. values are not very high?

B. Taylor

Verified customer

Asked: 2018-10-27

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. 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 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 MAG ELISA kit to have sensitivity of 50pg/ml, that means the minimum amount of MAG that can be declared/interpreted as positive by the above standard is 50pg/ml.

Question

Q: Can MAG ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

L. Chen

Verified customer

Asked: 2018-03-27

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 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 see 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: how many samples can be assayed in a Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2017-05-18

Answer

A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may vary slightly by kit so please refer to each datasheet for details.

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

R. Lopez

Verified customer

Asked: 2017-04-05

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

Question

Q: is it okay to use heparin plasma as samples in Human MAG Picokine® ELISA Kit (Catalog # EK2061)?

A. Young

Verified customer

Asked: 2014-12-14

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of MAG causing disruption of its protein structure. MAG 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 MAG ELISA, treating samples with different anticoagulants and decided that heparin, EDTA or citrate can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.
