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.

Ising is a Monte Carlo simulation of the two-dimensional Ising model, demonstrating phase transitions of a magnetic system. You can adjust the temperature, magnetic field, and lattice size (up to 400x400) while the simulation is running. Besides graphical output, the program keeps track of the current value, average, and standard deviation of the energy and magnetization, which you can copy and paste into a spreadsheet for further analysis.
This application provides an interface for running simulations of the Ising model of magnetically interacting spins on a 2-dimensional lattice. It is intended as a demonstration of the possibilities for interactive exploration of scientific models - the computing power available in modern machines is sufficient to perform sophisticated calculations on the fly as the parameters are changed.
Source code is also available via the IsingCocoa home page.
This is a small application which displays "Life" a simulation of cells which live & die by three simple rules. Life was created by John Conway and popularized in Scientific American's Mathematical Recreations column. A classic in the computer world.
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.
Live Deskpicture 3.1
An alternative to a static desktop picture - Install a self-updating time-zone map of the earth with day, night, twilight and city lights. The map updates automatically as the world turns. High resolution maps and graphics are individually crafted for 16 different monitor sizes from 800 x 600 all the way up to 2560 x 1600 pixels (The new Apple 30" display). While you work or while you leave your computer just sitting there, the newest desk picture keeps slipping behind your icons as often as you choose. The process repeats every time the earth rotates one pixel on your screen. Program operation is time-sliced in order to avoid interruptions of your work. The dock icon menu lets you highlight time zones to find the time at any worldwide location. If you are using two monitors, Live Deskpicture X works with either one or both.
Mac Brownian Motion 1.3b3
Mac Brownian Motion is a program that simulates (tah dah...) Brownian Motion. Brownian Motion is exhibited in a variety of situations, including motion of particles. Much of stochastic analysis (introduced in a graduate statistics program) is based on the properties of Brownian Motion. Physicists, engineers, economists, and statisticians all rely on its nice properties. It is primarily an educational tool. In fact, its purpose is (originally) rather narrow: to visualize Brownian Motion in one dimension over time.
MacClade is used as a tool for phylogenetic analysis. But by its nature it also embodies a world view, a portrayal of a phylogenetic approach to studying diversity and evolution. 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.
Researchers who want a simple, but comprehensive, desktop sequence analysis application continually turn to MacVector, the leading sequence analysis package for the Macintosh. MacVector provides sequence editing, primer design, Internet database searches, protein analysis, sequence confirmation, contig assembly capabilities, multiple sequence alignment, phylogenetic reconstruction, coding region analysis, and a wide variety of other functions. With MacVector, you can view the results of any analysis in graphical or text format.
Mesquite is software for evolutionary biology, designed to help biologists analyze comparative data about organisms. Its emphasis is on phylogenetic analysis, but some of its modules concern population genetics, while others do non-phylogenetic multivariate analysis.

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.

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.
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
