Calorimetric assay alp assay

Manufactured by Abcam

The Calorimetric assay ALP assay is a laboratory equipment used to measure the activity of the enzyme alkaline phosphatase (ALP) in a sample. The assay relies on the conversion of a colorless substrate into a colored product, which is then quantified using a spectrophotometer. The core function of this assay is to provide a quantitative assessment of ALP levels in various biological samples, such as serum, cell lysates, or tissue homogenates.

hMSCs were cultured for 14 days in differentiation induction medium prior to assessing differentiation. To analyze adipogenic differentiation, Adipo Red staining assay for staining intracellular triglycerides was performed on fixed cells as per manufacturer’s protocol (Lonza). For analyzing osteogenic differentiation, cells were either fixed or lysed at day 14. Alkaline phosphatase (ALP) was assessed by staining fixed cells using Fast Blue RR (Sigma) or by performing calorimetric assay ALP assay (Biovision Inc) on cell lysate as per manufacturer’s protocol. DNA content in cell lysate was determined by performing the PicoGreen assay (Life Technologies) as per manufacturer’s protocol. Analysis of ALP activity using calorimetric ALP assay was performed and represented after normalization by DNA content.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
