Icon AmplifX 1.37

The main purpose of AmplifX is to seek in a collection of primers, such as any molecular biologist will get in his refrigerators, those which can be used to amplify a fragment into a target sequence. For example, and particularly, to design strategies to screen recombinant clones by PCR. Some information is associated with each primer, some automatically computed by AmplifX (like TM, Quality, length) and others given by the user (name, comments,...) This allows general aspects of primer management (sequences and real tubes). AmplifX can also design new primers.

A plasmid Editor - It is designed to be an all-in-one molecular biology workbench. It can read strider, EMBL, genbank, Fasta sequence file formats. In addition it can read and display ABI trace files. It can query and download from the NCBI EMBL database and can blast sequences directly at the NCBI BLAST server. Sequence features can be added individually or automatically from pre-defined feature definition libraries. It can draw graphic (liear or circular) and text-based restriction maps that include annotated features of the sequence. It contains a restriction enzyme choser that can perform boolean queries for enzymes that match cut frequency and enzyme property parameters. It can show virtual agarose gels. It can align two sequences or a sequence and an ABI trace file. It can search selected sequence for potential PCR primers matching given parameters. All analysis functions are hyperlinked back to the original sequence.

You can drag-and-drop a crystal file into CrystalDiffract, or use CrystalMaker's Transform > Diffraction Pattern > Powder command to obtain a diffraction pattern for any displayed crystal structure.
Diffraction patterns can be displayed as traditional greyscale "films", or as diffractometer traces (graphs of intensity versus two-theta, d-spacing, 1/d, time-of-flight or energy). Tools allow you to measure peak positions, intensities, and their Miller indices. You can precisely scroll the diffraction pattern, or select a plot range and zoom. Other tool buttons provide scaling functions, as well as x and y-axis offsets.

Icon Gene Inspector 1.6.7

The Gene Inspector can perform many sophisticated sequence analyses, but this new software is much more than just another sequence analysis product. Imagine having the ability to define an entire suite of analyses to be performed each time you have a new sequence, and to design custom style sheets which specify exactly how your output will look for each analysis. Because you can predefine and store analysis parameters for any analysis to fit your needs, anyone in the lab will be able to obtain meaningful and consistent results, whether they are a novice just entering the lab, or an experienced researcher familiar with the analysis routines. The combination of notebook with navigation and drawing tools and sophisticated analyses provides the ability to annotate experimental results and analyses in a single location, rather than keeping your sequence analyses separate from you lab notes.

LifeLab is a Mac application for exploring John Conway's Game of Life and other cellular automata. CAs were first studied in the mid-1950s by Stanislaw Ulam and John von Neumann. The subject became much more widely known in 1970 when Life was described by Martin Gardner in his Scientific American column.
Life is played on an arbitrary-sized grid of square cells. Each cell has two states: "dead" or "alive". The state of every cell changes from one "generation" to the next according to the states of its 8 nearest neighbors: a dead cell becomes alive (a "birth") if it has exactly 3 live neighbors; a live cell dies out if it has less than 2 or more than 3 live neighbors. The "game" of Life simply involves starting off with a pattern of live cells and watching it evolve.

In fact, its purpose is (originally) rather narrow: to visualize Brownian Motion in one dimension over time.

It is relatively easy to see the diversity of living organisms, but it has proved more difficult to see that diversity in terms of its history; the slow development of a thoroughly phylogenetic perspective in biology attests to this challenge. Together the MacClade manual and program present methods for analyzing and exploring phylogenetic hypotheses, including hypotheses about character evolution. MacClade is one attempt to give our mind's eye phylogenetic lenses, to help us think about and see lineages and evolution.

Reconstruction of ancestral states (parsimony, likelihood)
Tests of process of character evolution, including correlation
Simulation of character evolution (categorical, DNA, continuous)
Parametric bootstrapping (integration with programs such as PAUP* and NONA)
Morphometrics (PCA, CVA, geometric morphometrics)

Icon MutantMaker 1.0

MutantMaker helps researchers performing site directed mutagenesis screen their potential mutants with restriction enzyme digests rather than costly sequencing. The oligonucleotide sequences suggested by MutantMaker will create or destroy restriction sites while both creating the desired mutant and retaining flanking amino acids.
Using a simple and elegant user interface, researchers enter their original DNA sequence into a text field, drag a codon selector over the codon to mutate, and choose how to mutate their selected amino acid.
MutantMaker has 492 unique restriction enzymes built right in, not including isoschizomers! Users can select any set of enzymes based on commercial availability or size.
MutantMaker results are even multi-colored showing exactly which nucleotides were mutated.
In typical fashion, results can be saved and reloaded for later use. And for reliability, data files are human-readable XML.

Icon Oligo 6.89

Oligo is a multi-functional program that searches for and selects oligonucleotides from a sequence file for polymerase chain reaction (PCR), DNA sequencing, site-directed mutagenesis, and various hybridization applications. It calculates hybridization temperature and secondary structure of oligonucleotides based on the nearest neighbor thermodynamic values.It is also a good tool for construction of synthetic genes, finding an appropriate sequencing primer among those already synthesized, finding and multiplexing consensus prmers and probes, and even finding potential restriction sites in a protein.
The Oligo software has been broadly accepted as the industry software standard for selecting and analyzing oligonucleotides for various molecular biology applications. The first commercial version of the software has been introduced in 1989.

Icon OligoChecker 2.21.25

A program to let you check which of your oligos you can use in a PCR for any given template (on my 1 GHz Powerbook it checks my 409 oligos against a 2 kB template in about 1.5 seconds).
Upon selecting two oligos for a PCR it will show the sequence (and inverted sequence) and size of the PCR product as well as the alignment of the oligos with the template.
It is not a program to help you design oligos - there are already programs out there which do this (e.g. the $1,200 Oligo, or online with Primer3).
Neither is it 's main purpose to run a PCR simulation

Icon The Periodic Table 1.4

It's a simple periodic table where you can click on the elements to display basic information: Symbol, Name, Atomic Number, Mass, and Phase under standard conditions. Double-clicking on an element will open a link to that element's wikipedia page for additional information. I've added the ability to select different elemental properties, and the table will remap the colors around these property values. This allows people to observe some basic periodic trends. The user preferences are also stored now, so the widget will always restart with the user's preferred style.
