Background of Angiopoietin-like Protein 7/ANGPTL7

Angiopoietin-related protein 7 is a protein that in humans is encoded by the ANGPTL7 gene. This gene is mapped to 1p36.22. Angiopoietin-like Protein 7 (ANGPTL7), also known as Corneal-Derived Transcript 6 (CDT6), is a secreted, 45‑50 kDa glycoprotein member of the angiopoietin‑like family of molecules. Members of this protein family contain an N-terminal coiled coil domain and a C-terminal fibrinogen-like domain. ANGPTL7 is expressed in the corneal stroma, trabecular meshwork, and sclera. Its production is up‑regulated in trabecular meshwork cells by glucocorticoids and TGF-beta and in cartilage by TNF-alpha. ANGPTL7 expression is up‑regulated under conditions of increased ocular pressure.

Question

Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measuring ANGPTL7 using the EK2035 Human ANGPTL7 Picokine® ELISA Kit?

H. Jha

Verified customer

Asked: 2020-05-03

Answer

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

Question

Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?

Verified Customer

Verified customer

Asked: 2019-12-22

Answer

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

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

G. Scott

Verified customer

Asked: 2019-08-13

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 a must for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question

Q: is it okay to use citrate plasma as samples in Human ANGPTL7 Picokine® ELISA Kit (Catalog # EK2035)?

D. Patel

Verified customer

Asked: 2019-01-26

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of ANGPTL7 causing degradation of its protein structure. ANGPTL7 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 ANGPTL7 ELISA, treating samples with a number of 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: What is the optimal O.D. value for ANGPTL7 ELISA kit? I performed your ANGPTL7 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 ANGPTL7 even though the O.D. values are not very high?

S. Patel

Verified customer

Asked: 2018-05-10

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. 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 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 ANGPTL7 ELISA kit to have sensitivity of 50pg/ml, that means the minimum amount of ANGPTL7 that can be declared/interpreted as positive by the above standard is 50pg/ml.

Question

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

H. Surve

Verified customer

Asked: 2018-03-02

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 depends upon the kit used so please refer to each datasheet for details.
