Background of TIMP-2

TIMP2 gen is encoded by 5 exons spanning 83 kb of genomic DNA. TIMP2 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.

9 Customer Q&As for Human 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?

Z. Robinson

Verified customer

Asked: 2020-05-08

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 proportion 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 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 2pg/ml, that means the minimum amount of TIMP-2 that can be declared/interpreted as positive by the above standard is 2pg/ml.

Question

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification TIMP-2 using the EK0522 Human TIMP-2 Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2018-11-10

Answer

A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample immediately after collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples in order to prevent protein degradation.

Q: Are Boster Bio recombinant proteins and antibodies sterile?

Verified Customer

Verified customer

Asked: 2018-10-02

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: can I use citrate plasma as samples in Human TIMP-2 Picokine® ELISA Kit (Catalog # EK0522)?

R. Green

Verified customer

Asked: 2018-01-04

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of TIMP-2 causing disruption 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 a must 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

Q: how much samples can be assayed in a Picokine® ELISA Kit?

J. Babu

Verified customer

Asked: 2018-01-03

Answer

A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may might differ by kit so please refer to each datasheet for details.

Question

Q: how to thaw whole blood sample for TIMP-2 ELISA after freezing?

Verified Customer

Verified customer

Asked: 2016-11-26

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 TIMP-2 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Boster Scientific Support

Answered: 2016-11-26

Question

Q: if the enzyme conjugated TIMP-2 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 TIMP-2 antigen?

A. Adams

Verified customer

Asked: 2016-07-04

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.
