Application examples

Application example

example

2 µg of total protein from various plant extracts (1-5) extracted with Agriera Protein Extraction Buffer PEB (AS08 300) separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Markers MagicMarks (Invitrogen) (M) and Rubisco protein standard (AS01 017S) at 0.0625 pmol, 0.125 pmol, 0.25 pmol.

Following standard western blot procedure this image has been obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad). The contour tool of the software is used to the area for quantitation and the values are background subtracted to give an adjusted volume in counts for each standard and sample.

Background

The Rubisco quantitation kit is suitable for quantitation of Rubisco in plant and algal samples using quantitative immunoblotting. It contains anti-RbcL antibody, Rubisco protein standard and the Protein Extraction Buffer for quantitative protein extraction. This kit is a good alternative to quantification of Rubisco by ELISA as it allows separation of Rubisco from a total complex cell protein mixture, which can be troublesome in case of ELISA method.
