Background of TRANCE/TNFSF11/RANK L
Receptor activator of nuclear factor kappa-B ligand (RANKL), also known as tumor necrosis factor ligand superfamily member 11 (TNFSF11), is a protein that in humans is encoded by the TNFSF11 gene. This gene encodes a member of the tumor necrosis factor (TNF) cytokine family which is a ligand for osteoprotegerin and functions as a key factor for osteoclast differentiation and activation. This gene is mapped to chromosome13q14.11. Targeted disruption of the related gene in mice led to severe osteopetrosis and a lack of osteoclasts. The deficient mice exhibited defects in early differentiation of T and B lymphocytes, and failed to form lobulo-alveolar mammary structures during pregnancy. This gene may play an important role in enhanced bone-resorption in humoral hypercalcemia of malignancy.

What exactly is the difference between Human TRANCE/RANKL/TNFSF11 PicoKine Quick ELISA Kit (FEK0842) versus Human TNFSF11/RANKL ELISA Kit PicoKine (EK0842)?
Verified customer
Asked: 2022-03-08
Answer
The main difference between FEK0842 and EK0842 is that FEK0842 (Quick ELISA) takes 90 minutes to run the assay while EK0842 takes the standard ~3 hours to run the assay. For FEK0842, the incubation times have been shortened while maintaining the quality of the product.

Question
Q: how can I thaw whole blood sample for TRANCE ELISA after freezing?
Verified Customer
Verified customer
Asked: 2020-10-21
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 TRANCE for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: is it okay to use citrate plasma as samples in Human TRANCE Picokine® ELISA Kit (Catalog # EK0842)?
H. Krishna
Verified customer
Asked: 2020-10-18
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of TRANCE causing degradation of its protein structure. TRANCE may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes a must for detection and block the antigen antibody reaction. We have tested the TRANCE 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 you suggest the dilution ratio of serum samples for detection of TRANCE in Human plasma? I am trying to measure a few parameters 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. Hernandez
Verified customer
Asked: 2019-06-14
Answer
A: without having an understanding 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 TRANCE 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

Q: What is the optimal O.D. value for TRANCE ELISA kit? I performed your TRANCE 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. can I consider these samples contain TRANCE even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2018-08-18
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. 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 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 TRANCE ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of TRANCE that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: Can TRANCE ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
M. Chen
Verified customer
Asked: 2015-02-07
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 a must. 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.

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 on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples to prevent protein degradation.
