製品の概要
Alanine Transaminase Activity Assay Kit (Colorimetric/Fluorometric) ab105134 is a rapid and simple assay used to quantify alanine transaminase (ALT) activity in mammalian samples.
In the ALT assay protocol, ALT transfers an amino group from alanine to α-ketoglutarate; producing pyruvate and glutamate. The pyruvate is detected in a reaction that converts a nearly colorless probe to a form that is colored (ODmax = 570 nm) and fluorescent (Ex/Em = 535/587 nm).
The kit has a detection limit of 10 mU per well.
ALT assay protocol summary:
- add samples and standards to wells
- add reaction mix and incubate for 10 min at 37ºC
- analyze every 2-3 min for 60 min with microplate reader in kinetic mode at 37ºC -
特記事項
This product is manufactured by BioVision, an Abcam company and was previously called K752 Alanine Aminotransferase (ALT or SGPT) Activity Colorimetric/Fluorometric Assay Kit. K752-100 is the same size as the 100 test size of ab105134.
Alanine transaminase is also called alanine aminotransferase or serum glutamic pyruvic transaminase (ALT, ALAT, SGPT).
Abcam has not and does not intend to apply for the REACH Authorisation of customers’ uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses. -

Liver samples from high fat diet (HFD) and standard carbohydrate diet (CHD) BALB/c and C57BL6/J mice were homogenised in an ALT assay buffer for the determination of ALT activity using ab105134. A separate batch of liver extracts was prepared and incubated in a buffer containing NP40 (5%) and supernatants containing the triglycerides were separated. Triglycerides concentration was determined on the supernatant fraction using ab65336. ALT activity and triglycerides concentration were determined by measuring OD at 570nm.
