Although the authors and publishers of the National Education Standards 1996 and the Benchmarks for Science Literacy 1993 claim that their recommendations are based on sound, extensive research about the way children learn, in fact the evidence is gen . . .

In Strongylocentrotus purpuratus the hyalins are a set of three to four rather large glycoproteins (hereafter referred to as ‘hyalin’), which are the major constituents of the hyaline layer, the developing sea urchin embryo's extracellular matrix. Rec . . .

For over a decade our laboratory has developed and used a novel histochemical assay using derivatized agarose beads to examine the surface properties of various cell types. Most recently, we have used this assay to examine lectin binding ligands on tw . . .

BackgroundQuantitative Polymerase Chain Reaction (qPCR) is a collection of methods for estimating the number of copies of a specific DNA template in a sample, but one that is not universally accepted because it can lead to highly inaccurate (albeit pr . . .

Alkaline lysis of Escherichia coli is usually the method of choice for plasmid preparation, but ''ghost bands" of denatured supercoiled DNA can result if the pH is too high or the period of lysis is too long. By replacing the usual sodium hydroxide ly . . .

We present an unusual and novel model for initial investigations of a putative role for specifically conformed glycans in cellular interactions. We have used α- and ß-amylase and α- and ß-glucosidase in dose–response experiments evaluating their effec . . .
