Background of GFR alpha-3/GDNF R alpha-3
GDNF family receptor alpha-3 (GFRα3), also known as the artemin receptor, is a protein that in humans is encoded by the GFRA3 gene. It is mapped to 5q31.2. The protein encoded by this gene is a glycosylphosphatidylinositol (GPI)-linked cell surface receptor and a member of the GDNF receptor family. It forms a signaling receptor complex with RET tyrosine kinase receptor and binds the ligand, artemin.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human GFRA3 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.

7 Customer Q&As for Human GFRA3 ELISA Kit PicoKine®
Question
Q: which procedure should I follow in order to thaw whole blood sample for GFR alpha-3 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-11-28
Answer
A: we do not recommend freezing 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 GFR alpha-3 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: if the enzyme conjugated GFR alpha-3 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 GFR alpha-3 antigen?
H. Johnson
Verified customer
Asked: 2020-10-04
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 you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2019-07-21
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: can you suggest the dilution ratio of serum samples for detection of GFR alpha-3 in Human plasma? I am trying to measure a few analytes 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: 2019-03-11
Answer
A: without knowing 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 GFR alpha-3 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: can I use EDTA plasma as samples in Human GFR alpha-3 Picokine® ELISA Kit (Catalog # EK2075)?
Verified Customer
Verified customer
Asked: 2019-01-02
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of GFR alpha-3 causing degradation of its protein structure. GFR alpha-3 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 GFR alpha-3 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.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
H. Walker
Verified customer
Asked: 2018-08-13
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.
