  • Product overview

    Amylase Assay kit (Colorimetric) (ab102523) detects activity of a-amylase through a two-step reaction. a-Amylase will cleave the substrate ethylidene-pNP-G7 to produce smaller fragments that are eventually modified by a-glucosidase, causing the release of a chromophore that can then be measured at OD = 405 nm. The assay can detect a-amylase content as low as 0.2 mU.

  • Notes

    Amylases are enzymes that break starch down to sugar molecules. a-amylase is the major form of amylase found in humans and other mammals as well as an enzyme present in seeds, or in fungi (baker's yeast for instance). a-amylase is a calcium metalloenzyme, completely unable to function in the absence of calcium. In human physiology, both the salivary and pancreatic amylases are major digestive enzymes. Increased enzyme levels in humans are associated with salivary trauma; mumps due to inflammation of the salivary glands, pancreatitis and renal failure. A simple, direct and automation-ready procedure for measuring a-amylase activity is, therefore, very desirable.

    Plasma amylase levels were measured (using ab102523) after 75 days treatment with saline, liraglutide, exendin-4 or sitagliptin. ND, normal chow diet; HFD, high fat diet. p≤0.05, *; p≤0.01, **, n = 3–7 mice.

    There were no statistically significant changes in plasma amylase activity in mice that were administered liraglutide or exendin-4 vs mice administered saline. However, administration of sitagliptin to animals on normal diet led to a 1.4-fold increase in amylase activity (p≤0.01, n = 3 per group) and a 1.3- fold increase in mice on a high fat diet (p≤0.01, n = 4 per group).

Amylase activity kits with chicken intestinal samples

 Excellent Excellent 5/5 (Ease of Use)
Abreviews
abreview image
The Amylase Assay Kit (ab102523) used to measure amylase activity in chicken intestinal samples worked well.
However, due to multiple attempts in trying to figure out the right dilution (between 1:50 and 1:400) of fresh samples and due to high individual variation, we managed to test the kits on a very small number of birds (9) since we used all the amylase substrate bottle provided (5ml) and the nitrophenol standard when preparing standard curves. Better to use three dilutions first and test it on a small number of samples, then continue the analysis with the final chosen dilution. It is advisable to have 2 kits as the nitrophenol standard is not enough to prepare at least 2 standard curve. One standard curve consumes 90 microliter of the solution, and the amount provided is 150 microl- It would have been better if it was at least 180 or 200 microliter.

Question

Are the two kits assay buffers the same? Can tissue extraction be performed using a phosphate buffer instead

Read More
Answer


These 2 kit buffers have different components and pH. They cannot be used interchangeably and it is not recommended to perform the extraction with PBS.

Question

Inquiry: Hello, I have a question regarding two kits: ab102523 (amylase) and ab102531 (trypsin). I have invertebrate tissues to analyse. I would like to extract those tissues with a phosphate buffer. Will this buffer be suitable with both kits? If so what pH do you recommend (7.5)? If the phosphate is not ok, can I use one of the kit buffer (amylase or trypsin?)?

Read More
Answer


The kit buffers would be ideal to extract your tissue. You can use the amylase assay buffer and the trypsin assay buffer.

Question

I have a few question about your product, Amylase Activity Assay Kit (ab102523).
1) Do you know whether this product react with any lipases?
2) Do you have a reaction formula about this product?
3) What did you use as a positive control?
4) If positive control is used with this kit, what is the activity value of it?"

Read More
Answer

Thanks.


We are not aware of any lipase interference in this assay.
The reaction principle is mentioned on our datasheet for this product. The complete organic reaction is proprietary information. The same goes for the positive control identity and activity as well. Sorry!

Question

Thank you for your kind response. As a matter of fact I would like to know if the kit has any guideline or manual which directly pointed on saliva as a sample site and also I would be so grateful if you let me know about probable other previous similar researches that had used your kit on saliva.
Best Regards

Question

Dear colleague
I'm XA conducting a research on occupational stress and willing to use your kit ab102523 for assaying alpha amylase on SALIVA, but in data you've provided the saliva has not been mentioned directly as the sample site. Please let me know if your kit can be used on measuring alpha amylase level in saliva.
Sincerely

Answer

Thank you for your telephone enquiry this morning.

I can confirm that this kit has not been specifically tested on rat samples, and so regrettably there is no data to provide. However, theoretically it should work in rat and so we can guarantee it for use in this species.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.
