We have previously identified a molecule (named cell adhesion molecule [CAM]) that is involved in the in vitro aggregation of neural cells from chick embryos. In the present report, specific anti-CAM antibodies have been used to demonstrate that CAM is localized in neural tissues, and is associated with the plasma membrane of retinal cells and neurites. Furthermore, it has been shown by antibod...

line, and the bulk of the tumour is disengaged from the peritoneal cavity and drawn outside the incision in the usual way. After attending to adhesions, the position of the appendages of the bladder, and of the rectum, are specially investigated and, if necessary, the uterine attachments of the broad ligaments are separated between double ligatures. Unless this is really necessary, it is much b...
متن کاملThe interpretation of current-clamp recordings in the cell-attached patch-clamp configuration.
In these experiments we have investigated the feasibility and accuracy of recording steady-state and dynamic changes in transmembrane potential noninvasively across an intact cell-attached patch using the current-clamp mode of a conventional patch-clamp amplifier. Using an equivalent circuit mimicking simultaneous whole-cell voltage-clamp and cell-attached current-clamp recordings we have defin...
متن کاملHow a DNA polymerase clamp loader opens a sliding clamp.
Processive chromosomal replication relies on sliding DNA clamps, which are loaded onto DNA by pentameric clamp loader complexes belonging to the AAA+ family of adenosine triphosphatases (ATPases). We present structures for the ATP-bound state of the clamp loader complex from bacteriophage T4, bound to an open clamp and primer-template DNA. The clamp loader traps a spiral conformation of the ope...
متن کاملThe Escherichia coli Clamp Loader Can Actively Pry Open the β-Sliding Clamp*
Clamp loaders load ring-shaped sliding clamps onto DNA. Once loaded onto DNA, sliding clamps bind to DNA polymerases to increase the processivity of DNA synthesis. To load clamps onto DNA, an open clamp loader-clamp complex must form. An unresolved question is whether clamp loaders capture clamps that have transiently opened or whether clamp loaders bind closed clamps and actively open clamps. ...
