  • Product overview

    Human Leptin ELISA kit is designed for the quantitative measurement of Human Leptin in serum, plasma, and cell culture supernatants.

    This assay employs an antibody specific for Human Leptin coated on a 96-well plate. Standards and samples are pipetted into the wells and Leptin present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Leptin antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Leptin bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

We used rhesus macaque serum/plasma with the human leptin kit and used human serum as a positive control. The human serum produced a strong signal but virtually no signal was produced by the rhesus macaque serum/plasma. Therefore, it is likely that this kit does not cross react with non-human primate serum/plasma.

Human Leptin ELISA test for rhesus macaques plasma

Excellent Excellent 5/5 (Ease of Use)
This ELISA kit is unsuitable for rhesus macaques. Undiluted plasma samples from 17 rhesus macaques yielded mostly negative or very weakly reactive positive results.

These products are very similar, they use similar techniques to measure human Leptin in samples. In reviewing the information about each kit I have noted that ab100581 Sensitivity< 2 pg/ml, Range of 1.64 pg/ml - 400 pg/ml and Recovery of 94%. While ab108879 has a Sensitivity of 0.12 ng/ml, Range of 0.125 ng/ml - 32 ng/ml, and Recovery = 99.5%. So differences are mainly in sensitivity and recovery.

Thank you for contacting us. We do not specifically have data on adolescents but can tell you that typically human urine does not have to be concentrated and can be diluted using the kit if necessary.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting us.

The differences of the two kits you are interested in are listed below. The most important difference is that one of the Kits is for detection of the Leptin Receptor, while the other kit is only detecting the secreted Leptin.

Thank you very much for your inquiry and your interest in our kits.

Unfortunately,the cross-reactivity of ab108879and ab108881 with pig samples is low, around 5%.

For the other three kits, ab100581, ab100718 and ab100773,the laboratory has not tested these on pig samples and no prediction can be made, as not all epitopes are known.

For the most part we do not see cross-species reactivity with sandwich based assays. If you would however nevertheless like to test on of these kits, please do let me know, as I would be able to provide you with an interesting testing offer.

Please do also let me know whether you would like to discuss other options. Indeed, we have many individual antibodies against leptin in our catalog as well. Some of them are tested in pig (ab3583 and ab16227) and others are tested in ELISA. Again, we could discuss options and provide testing offers if you are interested in this.

The testing offers would be along the line of the offer described here:

I hope this information is helpful. I am looking forward to hear back from you.

Thank you for contacting Abcam. Unfortunately, we do not have any cross reactivity data for rabbit samples on the ab100581 kit. Therefore we do not know if the kit will work with rabbit serum samples. Both the capture and detection antibody are monoclonal so unless the homology between human and rabbit is very high, I do not think that there would be any cross reactivity. Please let me know if there is anything else I can help with.
