Background of sFRP-5

Secreted frizzled-related protein 5 is a protein that in humans is encoded by the SFRP5 gene. SFRP5 is a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. SFRPs act as soluble modulators of Wnt signaling. SFRP5 and SFRP1 may be involved in determining the polarity of photoreceptor cells in the retina. SFRP5 is highly expressed in the retinal pigment epithelium, and moderately expressed in the pancreas.

8 Customer Q&As for Rabbit SFRP5 ELISA Kit PicoKine®

Question

Q: which procedure should I follow in order to thaw whole blood sample for sFRP-5 ELISA after freezing?

Verified Customer

Verified customer

Asked: 2020-05-11

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 sFRP-5 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question

Q: if the enzyme conjugated sFRP-5 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 sFRP-5 antigen?

W. King

Verified customer

Asked: 2020-01-29

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 long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement sFRP-5 using the EK1472-RB Rabbit sFRP-5 Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2019-10-10

Answer

A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may affect the stabilityof samples. It is recommend to assay sample on-stat 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.

Question

Q: Can sFRP-5 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2019-09-30

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 suitable 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 assessd 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 view 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: is it okay to use citrate plasma as samples in Rabbit sFRP-5 Picokine® ELISA Kit (Catalog # EK1472-RB)?

Verified Customer

Verified customer

Asked: 2019-09-06

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of sFRP-5 causing degradation of its protein structure. sFRP-5 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 sFRP-5 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 are cell lysates prepared for use in Picokine® ELISA kits?

Verified Customer

Verified customer

Asked: 2019-08-22

Answer

A: for 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.

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

A. Jackson

Verified customer

Asked: 2018-11-19

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.
