Background of GDF-5/BMP-14
Growth/differentiation factor 5 is a protein that in humans is encoded by the GDF5 gene. GDF5 is a protein belonging to the transforming growth factor beta superfamily that is expressed in the developing central nervous system, and has a role in skeletal and joint development. It also increases the survival of neurones that respond to the neurotransmitter dopamine, and is a potential therapeutic molecule associated with Parkinson's disease.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement GDF-5 using the EK1504-HA Chinese GDF-5 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-02-26
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may alter the stabilityof samples. It is recommend to assay sample right after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples in order to limit protein degradation.

Question
Q: how can I thaw whole blood sample for GDF-5 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-02-26
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 GDF-5 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 I use citrate plasma as samples in Chinese GDF-5 Picokine® ELISA Kit (Catalog # EK1504-HA)?
Verified Customer
Verified customer
Asked: 2019-10-22
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of GDF-5 causing degradation of its protein structure. GDF-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 GDF-5 ELISA, treating samples with a number of 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: Can GDF-5 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
C. Brown
Verified customer
Asked: 2019-10-01
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 required. 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 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: if the enzyme conjugated GDF-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 GDF-5 antigen?
Verified Customer
Verified customer
Asked: 2019-04-10
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: What is the optimal O.D. value for GDF-5 ELISA kit? I used your GDF-5 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 GDF-5 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2019-01-24
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 above example, 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 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 GDF-5 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of GDF-5 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2019-01-13
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 needed for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: we need your suggestion regarding the dilution ratio of serum samples for detection of GDF-5 in Chinese plasma? I am trying to measure a a number of 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.
P. Zhao
Verified customer
Asked: 2018-05-27
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 GDF-5 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: what is the protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?
S. Wu
Verified customer
Asked: 2017-07-04
Answer
A: for 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 can change immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.
