    Abcam's Ascorbic Acid Assay Kit provides a rapid, simple, and sensitive means of detecting ascorbic acid in various biological samples. In this assay, our proprietary catalyst oxidizes ascorbic acid to produce a product that interacts with the ascorbic acid probe, generating color and fluorescence. Ascorbic acid can be easily determined by either colorimetric (spectrophotometry at ? = 570 nm) or fluorometric (Ex/Em = 535/587 nm) methods. The assay can detect 0.01-10 nmol of ascorbic acid per assay in various samples.

  • 说明

    Ascorbic Acid (Vitamin C) plays an important role in many biological processes. It is a potent anti-oxidant, anti-inflammatory, anti-viral agent, and an immune stimulant and is present is a wide variety of foods and biological specimens. It is important to be able to monitor ascorbic acid content in these different samples.

I can confirm that the kit can be used with strawberry samples.

We recomend following guidelines for lysates preparation;

Homogenize the strawberries to homogeneity using the assay buffer in the kit and then centrifuge at top speed ...

In this assay, our proprietary catalyst oxidizes ascorbic acid to produce a product that interacts with the ascorbic acid probe, generating color and fluorescence. So if the vitamin C is already oxidized, it is l...

Frozen samples should be thawed at room temperature, then kept on ice and used promptly in the assay (not warmed to room temperature). Ab65346 is recommended for your samples, since they are already diluted and will be further diluted during the assay....

Thank you for your inquiry.

The lab was able to provide this information:

1 mole/lt is 1 M.
This standard is 20 µmole. You reconstitute it in 200 µl. That is 20 µmole/200 µl (or 100 µmole/ml which ...

Thank you for calling Abcam earlier today.

I have talked to the lab about whether the presence of EDTA in the samples would affect the kit and they say that it should be ok.

Please let me know if you have any more questions.

I understand your concern. Signal from pre-existing carbonyl groups, before the catalytic generation of  carbonyl from ascorbic acid, would be an issue with other samples types too, including serum and plasma. The background contributed by sample prote...

Thanks for your call this week and for your patience while I have been in touch with the lab about ab65346. This kit does utilize a reaction on carbonyl groups, so it will likely cross-react with the PVP though this has not been specifically tes...

Thank you for your inquiry. I just heard back from the testing laboratory that these kits cannot distinguish ascorbic acid isoforms. I am sorry that this information could not be more helpful, but please let us know if we can be of any other help.

Thank you for contacting us. I have hear back from the ab with the following information to your questions: 1. Yes, you can use plasma samples – but for ab65656 we recommend removing the proteins (e.g. by using spin filter (10 kDa cutoff) (ab933...

Thank you for your inquiry. Of the two kits, ab65656 is more suitable. Theoretically ab65656 should be compatible with plant samples as long as the lysates are prepared in the assay buffer provided in the kit. Technically though, since we have ...
