Background of TGF-beta 2
Transforming growth factor-beta 2 (TGF-beta 2) is a secreted protein known as a cytokine that performs many cellular functions and has a vital role during embryonic development. This gene is mapped to 1q41. It is an extracellular glycosylated protein. It is known to suppress the effects of interleukin dependent T-cell tumors. TGF-beta 2 is present at elevated levels in the aqueous humor of patients with primary open angle glaucoma (POAG). Studies have shown that TGF-beta 2 influences cultured trabecular meshwork cells, and it reduced outflow facility when perfused into cultured monkey primate anterior segments. In POAG, elevated expression of Gremlin by TM cells inhibited BMP4 antagonism of TGF-beta 2 and led to increased extracellular matrix deposition and elevated IOP.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Monkey primate TGF-Beta 2 ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

5 Customer Q&As for Monkey primate TGF-Beta 2 ELISA Kit PicoKine®
Question
Q: if the enzyme conjugated TGF-beta 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 TGF-beta 2 antigen?
P. Moore
Verified customer
Asked: 2020-11-07
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: What is the optimal O.D. value for TGF-beta 2 ELISA kit? I used your TGF-beta 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. is it safe to say these samples contain TGF-beta 2 even though the O.D. values are not very high?

Asked: 2018-09-14
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. 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. 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 TGF-beta 2 ELISA kit to have sensitivity of 10pg/ml, that means the minimum amount of TGF-beta 2 that can be declared/interpreted as positive by the above standard is 10pg/ml.

Question
Q: can I use heparin plasma as samples in Monkey TGF-beta 2 Picokine® ELISA Kit (Catalog # EK0981-PR)?
V. Williams
Verified customer
Asked: 2018-08-07
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can irreversibly bind metal ions from the functional domain of TGF-beta 2 causing degradation of its protein structure. TGF-beta 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 TGF-beta 2 ELISA, treating samples with a number of anticoagulants and decided that heparin, EDTA or citrate can be used for treatment of blood/plasma samples. Do not use other anticoagulents when collecting samples.
