When an investigator wants to replace one allele with an engineered construct but not affect any other locus in the genome, then the method of choice is homologous recombination . To perform homolgous recombination, you must know the DNA sequence of the gene you want to replace (figure 1). With this information, it is possible to replace any gene with a DNA construct of your choosing.
The Tocris molarity calculator is a useful tool which allows you to calculate the: mass of a compound required to prepare a solution of known volume and concentration volume of solution required to dissolve a compound of known mass to a desired concentration concentration of a solution resulting from a known mass of compound in a specific volume Calculate now! The molarity calculator equation The Tocris molarity calculator is based on the following equation:
The molarity calculator tool provides lab-ready directions describing how to prepare an acid or base solution of specified Molarity (M) or Normality (N) from a concentrated acid or base solution. To prepare a solution from a solid reagent, please use the Mass Molarity Calculator . To dilute a solution of known molarity, please use the Solution Dilution Calculator . How is the Molarity of a percentage solution calculated?
Records in REGISTRY represent substances indexed for the CAS databases (CA SM /CAplus SM , CASREACT ® , CHEMCATS ® , CHEMLIST ® , MARPAT ® ) and other databases in products such as SciFinder ® and STN ® . Substances that come from sources other than literature or patent publications may not contain any references. CAS indexes these substances to support registration policies, chemical libraries, chemical catalogs, web sources, reaction databases and data collections not represented in STN.

East Carolina University Department of Psychology Multivariate Analysis with SPSS Linked here are Word documents containing lessons designed to teach the intermediate level student how to use SPSS for multivariate statistical analysis.
This guide was compiled by Rosemary Trumbull, who obtained her Bachelors of Science in Biology-Psychology from Tufts University (2010). It is intended to provide resources for Neuroscience students, as well as people who are curious about the subject. The resource guide is divided into several broad categories, and each resource has a brief description of what can be found on that site. The resource guide includes links to databases, journals, societies, and laboratories that may help with Neuroscience students’ research.
The following is a selected list of resources to get you started in your neuroscience research. For further assistance, contact Dean Walton . Starting Your Research
12 August 2010 | Updated : 12 August 2010 0:00am Data Provided by Thomson Reuters from its Essential Science Indicators, January 2000-April 2010 The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the Thomson Reuters journal-to-category field-definition scheme. Individual papers published in influential multidisciplinary journals such as Nature and Science are also assigned to their appropriate fields.
