Background of Osteoprotegerin/TNFRSF11B
Osteoprotegerin (OPG) is identical to osteoclastogenesis inhibitory factor (OCIF), a soluble member of the tumor-necrosis factor receptor family that inhibits osteoclastogenesis. OPG is considered to play an important role in the regulation of bone resorption by modifying osteoclast differentiation. Osteoprotegerin is an independent risk factor for the progression of atherosclerosis and onset of cardiovascular disease. It can act as a soluble factor in the regulation of bone mass and imply a utility for OPG in the treatment of osteoporosis associated with increased osteoclast activity. OPG system may play a critical role in the development of osteolytic bone disease in multiple myeloma and that targeting this system may have therapeutic potential. OPG also plays a role in the vascular system.

Question
Q: Can Osteoprotegerin ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-11-03
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 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 check 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
We currently used your Mouse OPG (TNFRSF11B) / Osteoprotegerin ELISA Kit for testing in mouse plasma. I was wondering if there is any cross-reactivity with these antibody to human plasma.
Verified Customer
Verified customer
Asked: 2020-04-23
Answer
The antibody Mouse OPG (TNFRSF11B) / Osteoprotegerin ELISA Kit, the capture antibody is 100% cross reactivity with human OPG however, the detection antibody shows close to 0%, so when it used as a pair we cannot expect significant cross reactivity with human OPG.

Question
Q: can I use heparin plasma as samples in Mouse Osteoprotegerin Picokine® ELISA Kit (Catalog # EK0481)?
Verified Customer
Verified customer
Asked: 2020-04-02
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can sequester metal ions from the functional domain of Osteoprotegerin causing degradation of its protein structure. Osteoprotegerin may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the Osteoprotegerin ELISA, treating samples with different anticoagulants and decided that EDTA can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: which procedure should I follow in order to thaw whole blood sample for Osteoprotegerin ELISA after freezing?
D. Johnson
Verified customer
Asked: 2019-12-17
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 Osteoprotegerin 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 Osteoprotegerin 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 Osteoprotegerin antigen?
Verified Customer
Verified customer
Asked: 2019-03-03
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: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement Osteoprotegerin using the EK0481 Mouse Osteoprotegerin Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2018-11-15
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may alter the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to avoid protein degradation.

Question
Q: What is the optimal O.D. value for Osteoprotegerin ELISA kit? I performed your Osteoprotegerin 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 Osteoprotegerin even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-06-09
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. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. regarding your assay, 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. typically, 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 converting 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 Osteoprotegerin ELISA kit to have sensitivity of 5pg/ml, that means the minimum amount of Osteoprotegerin that can be declared/interpreted as positive by the above standard is 5pg/ml.

Question
Q: can you suggest the dilution ratio of serum samples for detection of Osteoprotegerin in Mouse serum? I am trying to measure a multiple 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.
Z. Varadkar
Verified customer
Asked: 2017-06-07
Answer
A: unable to understand 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 Osteoprotegerin 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.
