Image Studio™ Lite is free image processing software used for quantitation of Western blot images and images from related experiments.. As of 2021, Image Studio Lite has been discontinued and is no longer available for download.
Western blot workflow. The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. [1]
It is generally accepted, that while label-free quantification is the least accurate of the quantification paradigms, it is also inexpensive and reliable when put under heavy statistical validation. There are two different methods of quantification in label-free quantitative proteomics: AUC (area under the curve) and spectral counting.
To overcome this issue, two open resource databases have been created to display western blot results for antibodies that have good binding specificity within the expected range. [1] [16] [17] Furthermore, RPMAs, unlike western blots, do not resolve protein fractions by molecular weight. [1]
Normalization of Western blot data is an analytical step that is performed to compare the relative abundance of a specific protein across the lanes of a blot or gel under diverse experimental treatments, or across tissues or developmental stages.
This software analyzes differential quantification data and is assisted by tools and visualization options. It is possible to process label-free and tandem mass-tagged data.

At the protein level, the combined ratios a proteins' peptides represent the relative quantification of that protein. The MS/MS spectra can be analyzed using software that is freely available: i-Tracker [4] and jTraqX [5] [6]
[1] [2] Live single-cell studies can reveal key behaviours that would otherwise be masked in population averaging experiments such as western blots. [3] In a live single-cell imaging experiment a fluorescent reporter is introduced into a cell line to measure the levels, localisation or activity of a signalling molecule.
