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 Dog Caninea 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.

Question
Q: Can TGF-beta 2 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
P. Lopez
Verified customer
Asked: 2020-11-27
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is required. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been evaluated by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please view the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for measurement TGF-beta 2 using the EK0981-CN Dog TGF-beta 2 Picokine® ELISA Kit?
A. Liu
Verified customer
Asked: 2020-10-23
Answer
A: Boster Bio does not assess sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. avoid repeat freeze-thaw cycles with the stored samples to avoid protein degradation.

Question
Q: What is the optimal O.D. value for TGF-beta 2 ELISA kit? I performed 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?
S. Sunder
Verified customer
Asked: 2020-05-25
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 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 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 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: how much samples can be assayed in a Picokine® ELISA Kit?
Verified Customer
Verified customer
Asked: 2020-01-14
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 vary slightly by kit so please refer to each datasheet for details.

Question
Q: how are cell lysates prepared for use in Picokine® ELISA kits?
Verified Customer
Verified customer
Asked: 2017-12-23
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are included in the product insert. Components in lysate and lysis buffer can change immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question
Q: is it okay to use citrate plasma as samples in Dog TGF-beta 2 Picokine® ELISA Kit (Catalog # EK0981-CN)?
Verified Customer
Verified customer
Asked: 2016-06-21
Answer
A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of TGF-beta 2 causing disruption 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.

Question
Q: can you recommend the dilution ratio of serum samples for detection of TGF-beta 2 in Dog serum? I am trying to measure a multiple analytes and it requires 100ul of diluted samples for each well. We have low serum quantitys so we like to dilute as much as possible.
Y. Li
Verified customer
Asked: 2014-01-08
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 TGF-beta 2 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.
