Background of TIMP-2
TIMP-2 gen is encoded by 5 exons spanning 83 kb of genomic DNA. TIMP-2 is 83 kilobase pairs (kb) long with exon-intron splicing sites located in preserved positions among the three members of the TIMP family. The gene for tissue inhibitor of metalloproteinases-2 is localized on human chromosome arm 17q25. TIMP-2 abrogates angiogenic factor-induced endothelial cell proliferation in vitro and angiogenesis in vivo independent of MMP inhibition. The standard product used in this kit is recombinant human TIMP-2 with the molecular mass of 22Kda and 194 amino acid.

8 Customer Q&As for Rat TIMP-2 ELISA Kit PicoKine®
Question
Q: What is the optimal O.D. value for TIMP-2 ELISA kit? I used your TIMP-2 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 TIMP-2 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2020-05-24
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. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. considering 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 TIMP-2 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of TIMP-2 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: is it okay to use citrate plasma as samples in Rat TIMP-2 Picokine® ELISA Kit (Catalog # EK1302)?
G. Zhang
Verified customer
Asked: 2019-10-23
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of TIMP-2 causing degradation of its protein structure. TIMP-2 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 TIMP-2 ELISA, treating samples with various 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
Why are there precipitates in the samples diluent buffer for EK1302?
Verified customer
Asked: 2019-05-29
Answer
For the Rat TIMP-2 ELISA Kit PicoKine™ (EK1302), the precipitates are fatty substances contained in BSA. It would not affect the performace of the kit.

Question
Do you have information regarding the target epitope for the antibody in your TIMP2 ELISA kit?
Verified customer
Asked: 2019-04-22
Answer
Unfortunately, we do not do epitope mapping for our antibodies, so we are only able to provide the immunogen sequence.

Question
Have you tested EK1302 on urine samples? In your opinion, it would work?
Verified customer
Asked: 2019-03-01
Answer
We have not validated Rat TIMP-2 ELISA Kit PicoKine™ EK1302 with urine samples. In theory, the ELISA kit will work for all sample types if the target protein is present at a level that falls within the linear range of the ELISA kit detection range. We guarantee the kit to work on the sample types that we have tested. For sample types that we have not tested for, we suggest your customer run pilot experiments to decide the optimal sample dilution.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
D. Kumar
Verified customer
Asked: 2019-03-01
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 may impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: if the enzyme conjugated TIMP-2 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 TIMP-2 antigen?
Verified Customer
Verified customer
Asked: 2019-02-28
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: we need your suggestion regarding the dilution ratio of serum samples for detection of TIMP-2 in Rat serum? 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.
Verified Customer
Verified customer
Asked: 2018-03-09
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 TIMP-2 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.
