Strain Query FormThere are two options to view the RGD strain records: Option 1. Search by keyword or Option 2. By direct selection from a list of strains in RGD:Strain Search InstructionsThe RGD Strain records may be accessed in two different ways:
The rat strain data presented here is based on the Rat Strain List collected by Dr. M. Festing plus new strain data collected as part of the RGD curation effort. At the present time not all of the original Rat Strain List entries are loaded, work is underway to curate these remaining records during the summer of 2001. ACP Strain Heterozygote TableThis is a table showing the number of heterozygotic allele sizes detected when
48 strains were screened with 4000+ SSLPs. A completely inbred strain would
be expected to have very few (ideally zero) heterozygotic markers, higher numbers
of heterozygotic markers would suggest a less inbred strain. ACP Strain Polymorphism Percentage TableBased on the ACP data, this table indicates the percentage of polymorphic markers detected between two given strains. Two tables are presented, calculated using different criteria to define when two allele sizes are polymorphic between two strains. At its simplest, a marker is polymorphic between strain A and strain B if its allele size in Strain A is different to that in Strain B. These percentages are give in Table 1. However, this does not take into account the potential inaccuracies brought about by polyacrylamide gel electrophoresis, both at the gel running and gel reading stages. To account for this, we have recalculated the polymorphism percentages based upon saying that a marker is polymorphic between Strain A and Strain B if the difference in marker size between the two strains is greater than 2bp (Table 2). This results in a lower polymorphism rate between the strains but is perhaps a more accurate value.
NB These are both large HTML tables. |
