Background of TNF-alpha

Tumor necrosis factor-alpha (TNF-alpha, or TNF) is secreted by macrophages in response to inflammation, infection and cancer. Human Tumor Necrosis Factor (TNF) and Lymphotoxin (TNF-beta) are cytotoxic proteins which have similar biological activities and share 30% amino acid homology. TNF-alpha is produced by monocytes, which can stimulate endothelial cells to produce the multilineage growth factor granulocyte-macrophage colony-stimulating factor and extend the role of this immunoregulatory protein to the regulation of hematopoiesis in vitro. TNF is a soluble protein that causes damage to tumor cells but has no effect on normal cells. Human TNF has been purified to apparent homogeneity as a 17.3-kilodalton protein from HL-60 leukemia cells and has showed cytotoxic and cytostatic activities against various human tumor cell lines. The human TNF cDNA is 1585 base pairs in length and encodes a protein of 233 amino acids. The mature protein begins at residue 77, leaving a long leader sequence of 76 amino acids. TNF-alpha has been mapped to human chromosome 6.

Question

Q: if the enzyme conjugated TNF-alpha antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the TNF-alpha antigen?

Y. Banerjee

Verified customer

Asked: 2020-05-09

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 I use citrate plasma as samples in Mouse TNF-alpha Picokine® ELISA Kit (Catalog # EK0527)?

W. Gonzalez

Verified customer

Asked: 2019-12-03

Answer

A: Chelating agents such as EDTA, Heparin and Citrate can attach metal ions from the functional domain of TNF-alpha causing degradation of its protein structure. TNF-alpha 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 TNF-alpha 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: What is the optimal O.D. value for TNF-alpha ELISA kit? I performed your TNF-alpha 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. can I consider these samples contain TNF-alpha even though the O.D. values are not very high?

Verified Customer

Verified customer

Asked: 2019-09-26

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 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 TNF-alpha ELISA kit to have sensitivity of 1pg/ml, that means the minimum amount of TNF-alpha that can be declared/interpreted as positive by the above standard is 1pg/ml.

Question

Can the sample diluent buffer, ABC diluent buffer and antibody diluent buffer be used interchangeably between the kit?

Verified customer

Asked: 2019-05-28

Answer

For the Mouse IL-1 Beta ELISA Kit PicoKine™ (EK0394), Mouse MCP-1 ELISA Kit PicoKine™ (EK0568), Mouse TNF Alpha ELISA Kit PicoKine™ (EK0527), Mouse IL-6 ELISA Kit PicoKine™ (EK0411) and Mouse Adiponectin ELISA Kit PicoKine™ (EK0596), the sample diluent buffer, ABC diluent buffer and antibody diluent buffer can be used interchangeably between the kit. However, the sample diluent buffer can only be used to dilute standards and samples, ABC diluent buffer is used to dilute ABC only and antibody diluent buffer is used to dilute antibody only.

Question

Q: Can TNF-alpha ELISA Kits be used with tissue homogenates (or other non-validated sample types)?

Verified Customer

Verified customer

Asked: 2019-02-06

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 a must. 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 assessd 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 check 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

I would like to ask at what concentration of Mouse TNF alpha is measured in normal mouse plasma samples?

Asked: 2019-01-24

Answer

Yes, it can detect your samples and we would recommend the starting dilution factor is 2-fold to reduce the risk of matrix effects. So, there is a wide range of possible detected levels, and some troubleshooting and optimization may be necessary if the samples contain a low level of the analytes.

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 have an affect on immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question

Q: which procedure should I follow in order to thaw whole blood sample for TNF-alpha ELISA after freezing?

Verified Customer

Verified customer

Asked: 2017-11-06

Answer

A: do not freeze 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 TNF-alpha for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.
