    Description / Table of Contents: This new edition of Fluorescent Proteins presents current applications of autofluorescent proteins in cell and molecular biology authored by researchers from many of the key laboratories in the field. Starting from a current review of the broad palette of fluorescent proteins available, several chapters focus on key autofluorescent protein variants, including spectral variants, photodynamic variants as well as chimeric FP approaches. Molecular applications are addressed in chapters that detail work with single molecules, approaches to generating protein fusions and biosensors as well as analysis of protein-protein interactions in vivo by FRET, fluorescence polarization and fluorescence cross correlation techniques. A number of approaches to in vivo dynamics are presented, including FRAP, photoactivation, and 4-dimensional microscopy. Behavior of spindle components, membrane proteins, mRNA trafficking as well as analysis of cell types in tissues and in development are detailed and provide models for a wide variety of experimental approaches. In addition, several chapters deal directly with the computational issues involved in processing multidimensional image data and using fluorescent imaging to probe cellular behavior with quantitative modeling. This volume brings together the latest perspective and techniques on fluorescent proteins and will be an invaluable reference in a wide range of laboratories.

    Notes: The seepage meter and the mini-piezometer were utilized in an attempt to evaluate ground-water reservoir interactions over a 12-month period at Echo Bay in Lake Mead. In conjunction with these techniques three standard piezometers, refraction seismic data, and water chemistry data were utilized to interpret seepage device results. During a four-month period, from December 1979 to March 1980, an 8 ft (2.5 m) rise in reservoir stage, the reservoir contributed water to Echo Wash bank storage at rates of up to 0.29 gpd/ft2 (12 lpd/m2). Ground-water discharge occurred for the remainder of the project, during a stage decline from April 1980 to May 1980, a rise in June 1980, and leveling off and slight decline for the remainder of the year, July 1980 to December 1980. The maximum seepage meter ground-water discharge rate of 3.0 gpd/ft2 (122 lpd/m2) was recorded in December 1980. Seepage meter water chemistry data for June were similar to Lake Mead water chemistry and were interpreted to be previously recharged Lake Mead water. September water chemistry data showed two possible components of ground-water discharge, a high SpC calcium sulfate Echo Wash ground water and a lower SpC Lake Mead recharged bank storage water. December ground-water chemistry data showed discharge to be a high SpC calcium sulfate water similar to Echo Wash ground-water quality which was apparently unaffected by Lake Mead inflow. Mini-piezometer data were collected at each seepage meter site. However, these data usually did not provide correlative results with seepage meter data probably because of suspended sediment in the piezometer water column and plugging of the perforated tip. Seepage meters were successfully utilized to characterize reservoir ground-water interaction in Echo Bay.

    Notes: Abstract: Tubulin, isolated from brain tissue of chicks at different stages during late embryonic and early posthatched development by ion-exchange chromatography and by in vitro microtubule reassembly, was analyzed by high-resolution isoelectric focusing and by two-dimensional polyacrylamide gel electrophoresis. Similar results were obtained with tubulins purified by the two methods. Sixteen isoelectric species of tubulin that differ in apparent net charge under denaturing conditions were detected by isoelectric focusing. By two-dimensional polyacrylamide gel electrophoresis, the chick brain tubulins were resolved into at least seven forms of α and 10 forms of β tubulin. The number and relative proportions of the maltiple brain tubulins were modulated during development. Since there are only four α tubulin and four β tubulin genes in chickens, posttranslational modification of the tubulins must play a prominent role in the heterogeneity. Analysis of isotubulin distributions through cycles of microtubule assembly and disassembly indicated that the tubulins differ very little, if at all, in their capacity to assemble into microtubules. Therefore, the chemical differences that distinguish the multiple tubulins have very little structural impact on the protein surface areas involved in microtubule formation. Partial fractionation of the multiple tubulins during ion-exchange chromatography was observed, suggesting that it may be possible to isolate individual native tubulin variants for biochemical studies.
