Background of Bdnf
Brain-derived neurotrophic factor (BDNF) is a prosurvival factor induced by cortical neurons that is necessary for survival of striatal neurons in the brain. It is a secreted protein with the molecular weight of 27.8kDa, consisting of 247 amino acids. It is known to promote neuronal survival and differentiation. BDNF shares substantial amino acid sequence identity with nerve growth factor (NGF). BDNF and neurotrophin-3 (NT-3) are two recently cloned neurotrophic factors that are homologous to NGF. mRNA products of the BDNF and NT-3 genes are detected in the adult human brain, suggesting that these proteins are involved in the maintenance of the adult nervous system. BDNF and other neurotrophins are critically involved in long-term potentiation (LTP). BDNF-mediated LTP is induced postsynaptically. BDNF has trophic effects on serotonergic (5-HT) neurons in the central nervous system. BDNF has an essential maintenance function in the regulation of anxiety-related behavior and in food intake through central mediators in both the basal and fasted state. It plays a role in treating breathing disorders such as respiratory insufficiency after spinal injury.

Question
Is this kit compatible with tissue homogenates taken from Wistar rats hippocampus and hypothalamus?
Verified customer
Asked: 2021-12-15
Answer
Our lab hasn't worked on tissue lysates with EK0308. Endogenous biotin in tissue homogenates might introduce false positive signal. We recommend the customer to run a pilot test as described below to confirm the affect of endogeous biotin first. Add tissue homogenates into the wells and then add ABC abd TMB without adding any biotinylated detection antibody to see if any signal will be observed. If no signal is produced, the customer can work on the tissue sample by using the kit. Please see the following suggested protocol. Procedure for Lysis of Tissues Note: Pre-chill an appropriate volume of IP Lysis Buffer at 4 ˚C. If desired, add protease inhibitor and phosphatase inhibitor to the lysis buffer immediately before use. 1.Place the fresh tissue into chilled PBS and rinse several times. Mince the tissue into small pieces. 2.Add IP lysis buffer to the tissue. We recommend the customer to use lysis buffer from Thermofisher. https://www.thermofisher.cn/order/catalog/product/87788?SID=srch-srp-87788#/87788?SID=srch-srp-87788 3.Homogenize for several minutes with a glass homogenizer at high speed until no tissue chunks remain. 4.Incubate on ice for 10 minutes. 5.Centrifuge at ~13000 x g for 10 minutes at 4°C. 6.Transfer supernatant to a new tube for further analysis.

Question
Q: is it okay to use EDTA plasma as samples in Rat Bdnf Picokine® ELISA Kit (Catalog # EK0308)?
T. Kulkarni
Verified customer
Asked: 2020-11-18
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can bind metal ions from the functional domain of Bdnf causing degradation of its protein structure. Bdnf 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 Bdnf ELISA, treating samples with a number of anticoagulants and decided that heparin, EDTA or citrate can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.

Question
Q: Can Bdnf ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-11-10
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. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: can you suggest the dilution ratio of serum samples for detection of Bdnf in Rat plasma? I am trying to measure a a number of analytes and it requires 100ul of diluted samples for each well. We have limited sample quantitys so we like to dilute as much as possible.
Verified Customer
Verified customer
Asked: 2020-02-15
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 Bdnf 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 optimal O.D. value for Bdnf ELISA kit? I performed your Bdnf 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 Bdnf even though the O.D. values are not very high?
P. Allen
Verified customer
Asked: 2019-11-02
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 example mentioned, 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. 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 Bdnf ELISA kit to have sensitivity of 15pg/ml, that means the minimum amount of Bdnf that can be declared/interpreted as positive by the above standard is 15pg/ml.

Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are present in the product insert.
