Weighing the sample is still considered the Gold-Standard practice for calprotectin extraction. You can read more about the weighing extraction procedure here.
However, due to the nature of samples, products have been developed in order to minimise sample handling time. Alpha Laboratories offers three key products for the extraction of human faecal Calprotectin for laboratories, clinicians and point of care applications in the UK.
Choose from one of the following products:
CALEX® Cap is a brand new stool extraction device containing a measured amount of BÜHLMANN calprotectin extraction buffer. It is for exclusive use with all BÜHLMANN calprotectin assays.
The features of the CALEX extraction device are unique in the market. It improves laboratory workflow and efficiency by eliminating the need for sample weighing, pipetting or decanting and enabling direct loading of the extraction device onto ELISA processors.
CALEX Cap can be used directly with:
Laboratories using CALEX Cap can benefit from the new BÜHLMANN Calprotectin ELISA kit format EK-CAL2-WEX, that is provided without extraction buffer and so reduces cost and waste.
Using Quick-Prep, sample preparation is reduced from 7 steps (in the weighing extraction method) to just 5 steps.
This device is best for “Nutella-like“ faeces, faeces containing fibres or grains.
Extraction tubes are ordered separately for the Quantum Blue and EK-CAL ELISA.
Using the Roche Smart-Prep device, you can reduce sample preparation from 7 steps (in the weighing extraction method) to just 5 steps.
Simplifies and aids more accurate extraction of Calprotectin from stool samples.
This device is best for liquid faeces or very dry faeces.
Extraction tubes are ordered separately.
