Background of Matrilin-4
Matrilin-4 is a 73 kDa secreted glycoprotein that is a member of the matrilin family of the von Willebrand Factor-A (vWA) domain-containing superfamily. This gene is mapped to 3q42. Matrilins are modular extracellular matrix proteins that serve as adaptors and linkers for other matrix proteins. Matrilin-4, like Matrilin‑2, has a broad distribution in both cartilage and in loose connective tissue such as dermis, lung and kidney, while Matrilins 1 and 3 are limited to cartilage. Matrilin-4 is present in nervous tissue and is abundant in the brain. Mature mouse Matrilin-4 shares 98%, 90%, 89% and 66% amino acid (aa) identity with rat, human, canine and chicken Matrilin-4, respectively. The 624 aa mouse Matrilin-4 contains a 22 aa signal sequence, two potential glycosylation sites, and four cysteine-rich EGF-like domains placed between two vWA domains. A short isoform lacks the N-terminal vWA domain (aa 28‑217). A C-terminal alpha -helix/coiled-coil region (aa 590‑623) by which multimers are formed is often proteolytically removed so that Matrilin-4 is found as a mixture of monomers with homo- or hetero- dimers and trimers. Matrilin-4 forms multimers with Matrilins 1 and 2 but not with Matrilin-3. The N-terminal vWA domains of Matrilins associate with collagen IV microfibrils via the proteoglycans biglycan and decorin, linking the fibrils with other matrix constituents aggrecan and collagen II. Matrilins also show calcium-dependent binding to the cartilage oligomeric matrix protein (COMP); this interaction is of high affinity for oligomeric Matrilin-4 and somewhat lower affinity for monomeric Matrilin-4. Functions and distributions of Matrilins overlap enough so that knockouts of Matrilins 1, 2 and 3 lack obvious phenotypes.

Question
Q: for how much duration can samples (cell cultures, serum, and plasma) be stored and still be stable for quantification Matrilin-4 using the EK2031 Rat Matrilin-4 Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-08-05
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 immediately after collection when possible, or aliquot into single use volumes and store samples frozen. limit repetitive freeze-thaw cycles with the stored samples to limit protein degradation.

Question
Q: is it okay to use citrate plasma as samples in Rat Matrilin-4 Picokine® ELISA Kit (Catalog # EK2031)?
Verified Customer
Verified customer
Asked: 2018-06-14
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of Matrilin-4 causing degradation of its protein structure. Matrilin-4 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 Matrilin-4 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: can you recommend the dilution ratio of serum samples for detection of Matrilin-4 in Rat plasma? I am trying to measure a few 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: 2017-10-04
Answer
A: unable to know 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 Matrilin-4 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: which procedure should I follow in order to thaw whole blood sample for Matrilin-4 ELISA after freezing?
Verified Customer
Verified customer
Asked: 2017-08-05
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 Matrilin-4 for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

T. Gandhi
Verified customer
Asked: 2014-04-20
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: What is the optimal O.D. value for Matrilin-4 ELISA kit? I performed your Matrilin-4 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 Matrilin-4 even though the O.D. values are not very high?
Verified Customer
Verified customer
Asked: 2014-03-20
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 Matrilin-4 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of Matrilin-4 that can be declared/interpreted as positive by the above standard is 10pg/ml.
