GFP-Pen is a handheld, battery-powered fluorometer that provides rapid and accurate readings of Green Fluorescent Protein (GFP) emission. Equipped with a leaf-clip, the device allows rapid, repeated and non-destructive GFP determinations in intact leaf samples. Affordable price and simple two-button operation makes the GFP-Pen a perfect tool for studying the difference between the high and low GFP expressing plants and between the transformed and non-transformed organisms.
Green Fluorescent Protein (GFP) serves as a genetic marker in genetically modified plants and as a very useful tool in gene expression studies. The GFP-Pen can be used for tracking the expression of these modified genes in crops. It allows quick field or laboratory screening of multiple samples with a very high degree of accuracy.
