Background of FOLR1
Folate receptor 1 adult is a protein that in humans is encoded by the FOLR1 gene. The protein encoded by this gene is a member of the folate receptor (FOLR) family. It is mapped to 11q13.4. FOLR1 expression in Jurkat cells facilitated MBG or EBO entry, and FR-blocking reagents inhibited infection of MBG or EBO. This gene product is a secreted protein that either anchors to membranes via a glycosyl-phosphatidylinositol linkage or exists in a soluble form. The FOLR1 gene encodes the adult folate receptor, or folate-binding protein (FBP), which has a high affinity for folic acid and for several reduced folic acid derivatives, and mediates delivery of 5-methyltetrahydrofolate to the interior of cells. FOLR1 is also an important regulator of milk protein synthesis.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human FOLR1/Alpha Fr 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 FOLR1/Alpha Fr ELISA Kit PicoKine®
Question
Q: is it okay to use citrate plasma as samples in Human FOLR1 Picokine® ELISA Kit (Catalog # EK1242)?
G. Bhasin
Verified customer
Asked: 2020-01-12
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of FOLR1 causing degradation of its protein structure. FOLR1 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 FOLR1 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 can I thaw whole blood sample for FOLR1 ELISA after freezing?
T. Young
Verified customer
Asked: 2019-08-01
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 FOLR1 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of FOLR1 in Human urine? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
V. Parker
Verified customer
Asked: 2018-12-16
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 FOLR1 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: if the enzyme conjugated FOLR1 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 FOLR1 antigen?
Verified Customer
Verified customer
Asked: 2016-04-01
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?
P. Parker
Verified customer
Asked: 2016-01-01
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included 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.
