Background of beta-NGF
Nerve growth factor (NGF) is a polypeptide involved in the regulation of growth and differentiation of sympathetic and certain sensory neurons. NGF is thought to have a profound effect on the development and maintenance of sympathetic and embryonic sensory neurones. NGF activity isolated from the male mouse submaxillary gland (MSG) consists of three types of subunits, alpha, beta and gamma, which specifically interact to form a 7S, approximately 130,000-molecular weight (Mr) complex. The 7S complex contains two identical 118-amino acid beta-chains, which are solely responsible for the nerve growth-stimulating activity of NGF. NGF, which is expressed by inflammatory cells and effects changes that lead to increased neural responsiveness, could be a pivotal mediator in allergic rhinitis.

Question
Hi I have a question for EK0470. My sample type is mouse plasma and prepared in a following way: A plasma sample will be prepared as follows: whole blood will be placed into an (+4°C) precooled K2-EDTA tube (and kept cold). The tube will be gently turned a few times to fully mix the blood and centrifuged at 2000 g (+4°C) for 10 min within 30 minutes. Questions: 1) Is the plasma isolation protocol ok for this kit? 2) The kit states that plasma should be stored at -20. Can we store the plasma also at -80C? 3) would you have any experience what dilution would be used for the mouse plasma samples (are 1:2, 1:5 and 1:10 possibly good dilutions to be tested)? Thank you for the help, and looking forward to hearing from you.

Thank you for your inquiry. Please see the following information. 1) Is the plasma isolation protocol ok for this kit? The protocol is OK. 2) The kit states that plasma should be stored at -20. Can we store the plasma also at -80C? The plasma can be stored at -80C. 3) would you have any experience what dilution would be used for the mouse plasma samples (are 1:2, 1:5 and 1:10 possibly good dilutions to be tested)? 1:1 is suggested (e.g. Add 50μl sample to 50 μl sample diluent buffer). We hope our response has satisfied your request. Should there be any questions, please feel free to contact us. We would be more than happy to help.

Question
Q: how to thaw whole blood sample for beta-NGF ELISA after freezing?
M. Singh
Verified customer
Asked: 2020-12-09
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 beta-NGF 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 beta-NGF antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the beta-NGF antigen?
Verified Customer
Verified customer
Asked: 2020-07-27
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 beta-NGF ELISA kit? I used your beta-NGF 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 beta-NGF even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2020-06-23
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. an important assessment 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 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 beta-NGF ELISA kit to have sensitivity of 1pg/ml, that means the minimum amount of beta-NGF that can be declared/interpreted as positive by the above standard is 1pg/ml.

Q: Are Boster Bio recombinant proteins and antibodies sterile?
T. Taylor
Verified customer
Asked: 2020-05-22
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.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis beta-NGF using the EK0470 Mouse beta-NGF Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-04-17
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-stat 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: Can beta-NGF ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-04-16
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.

Q: how are cell lysates prepared for use in Picokine® ELISA kits?
L. Martin
Verified customer
Asked: 2017-12-01
Answer
A: in those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found 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.
