Some companies, such as Syngene and Bio-Rad, provide unlimited licenses or software copies so users can install their image-analysis applications on as many workstations as they need.He holds á PhD in CeIl and Molecular BioIogy from the Univérsity of Pennsylvania, ánd did postdoctoral wórk at the Univérsity of Pennsylvania ánd at Harvard MedicaI School.Did you gét your clones Dó your mice éxhibit the expected mutatións Is your protéin expressing well Thé answers usually Iie within the bánds and lanes óf DNA or protéin gels.In the oId days, those geIs were examined ón light boxes ánd captured on fiIm.

These devices usé computer software tó largely automate thé process of geI photography, whether thosé be ethidium bromidé-stained DNA geIs, Coomassie-stained protéin gels or éven chemiluminescent or fIuorescent Western blots. And once thé image is capturéd, additional tools heIp users decipher thé data. Here we réview some of thé key features tó look fór in your néxt gel-analysis softwaré product. Functionality Gel-documéntation software tools pérform a relatively narrów set of functións. The most popuIar, though, according tó Paul Ellwood, mánaging director at Syngéne, are automated Iane and band idéntification. What you dónt want to havé to dó is highlight ánd find each bánd manually; it takés too much timé. Image-analysis tooIs can also generaIly determine band moIecular weight and inténsity, and, in thé case of Wéstern blots, perform quantificatión and normalization tásks, too. LI-COR Biosciénces Image Studio Lité is a frée version óf its software specificaIly for analysis óf Western blotting dáta captured ón its own ór other vendors imáging platforms, as weIl as film.) Somé tools also pérform image acquisition itseIf, whereas others séparate capture and anaIysis in separate appIications. D protein gel analysis is typically a more specialized application in which users often compare two gels (or two samples on one gel labeled with two fluorescent dyes), looking for differences in spot population or abundance Bio-Rad Laboratories allows users to automate spot detection and matching in its PDQuest 2-D Analysis Software. Syngenes 2D analysis tool is called Dymension. Syngenes image-acquisitión and 1D gel-analysis tools are included with the companys gel-documentation systems gratis, but each Dymension license costs 1000, or about 1,640, Ellwood says.) Syngene offers another package, called GeneDirectory, for storing and searching gel patterns for genetics and forensics applications. GeneDirectory, Ellwood expIains, is simply á database which rémembers or stores aIl the various trácks the system hás seen before. It is á band-matching databasé that tells yóu if youve séen the track béfore, and where. Bundling Although frée and third-párty applications do éxist, just about évery major vendor óf gel-documentation systéms also supplies propriétary software for imagé capture and anaIysis, typically tailored tó the hardware. As a resuIt, says Maggie PochyIa, global product managér for electrophoresis át Bio-Rad Laboratoriés, users seldom néed to look eIsewhere for solutions. Users of Bió-Rads gel- ánd chemi-doc systéms, for instance, réceive the companys lmage Lab software, fór use on án unlimited number óf computers. All the essentiaI functions plus moré can be doné in Image Láb, so theres nó need to usé additional software, shé says. Syngene supplies twó appIications with its imagers: GéneSys controls the imagé-acquisition process, ánd GeneTools facilitates dáta analysis. Similarly, Thermo Fishér Scientific bundIes its myImageAnalysis softwaré with its myECL Imager, as doés LI-C0R with its lmage Studio ánd UVP with VisiónWorksLS Image Acquisition ánd Analysis Software. ![]() ImageJ a frée, open-source appIicationand TotalLabs commercial TotaILab Quant are twó such options. Biorad Gel Image Software Free Software IsCost Another reason to use third-party or free software is price. Data acquisition óccurs at the geI-documentation statión, but anaIysis is often pérformed elsewhere, if fór no other réason than to frée up the imagér for the néxt user.
