Background of ADAMTS4

ADAMTS4, A disintegrin and metalloproteinase with thrombospondin motifs 4 is an enzyme that in humans is encoded by the ADAMTS4 gene. ADAMTS4 is a member of the large ADAMTS family of zinc-dependent proteases. The human ADAMTS4 gene is mapped to chromosome 1 by somatic cell hybrid analysis. The enzyme encoded by this gene lacks a C-terminal TS motif. It is responsible for the degradation of aggrecan, a major proteoglycan of cartilage, and brevican, a brain-specific extracellular matrix protein. The cleavage of aggrecan and brevican suggests key roles of this enzyme in arthritic disease and in the central nervous system, potentially, in the progression of glioma.

9 Customer Q&As for Human ADAMTS4 ELISA Kit PicoKine®

Question

Q: can I use citrate plasma as samples in Human ADAMTS4 Picokine® ELISA Kit (Catalog # EK1372)?

Verified Customer

Verified customer

Asked: 2020-10-01

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of ADAMTS4 causing disruption of its protein structure. ADAMTS4 may be denatured as a result and may compromise the assay's measurements. The chilating sites could also be too close to the epitopes needed for detection and block the antigen antibody reaction. We have tested the ADAMTS4 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 long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis ADAMTS4 using the EK1372 Human ADAMTS4 Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2019-10-29

Answer

A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may affect 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 to limit protein degradation.

Question

Q: What is the optimal O.D. value for ADAMTS4 ELISA kit? I performed your ADAMTS4 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 ADAMTS4 even though the O.D. values are not very high?

H. Smith

Verified customer

Asked: 2019-08-11

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. what you should focus on is whether your sample O.D. values are statistically significantly higher than your blank values. regarding your protocol, 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 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 ADAMTS4 ELISA kit to have sensitivity of 20pg/ml, that means the minimum amount of ADAMTS4 that can be declared/interpreted as positive by the above standard is 20pg/ml.

Question

Q: if the enzyme conjugated ADAMTS4 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 ADAMTS4 antigen?

V. Mangal

Verified customer

Asked: 2019-08-10

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: can you recommend the dilution ratio of serum samples for detection of ADAMTS4 in Human serum? I am trying to measure a multiple 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: 2019-01-12

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 ADAMTS4 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 protocol regarding preparation of cell lysates prepared for use in Picokine® ELISA kits?

Verified Customer

Verified customer

Asked: 2016-12-18

Answer

A: for 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 effect immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.
