Structural and mechanical analysis of the black widow spider web subjected to stretching, expansion and wind
The web of the black widow is apparently a random spatial arrangement of threads, which provides its occupant with housing, means to capture prey and protection. However to ensure that these functions are fulfilled, the spider has evolved to adapt the architecture of the web so that it would be …

Expression, purification, and characterization of a novel cysteine-rich silk protein expressed in the tubuliform and aggregate glands of the black widow spider : a thesis
<p>Belonging to the diverse order Araneae, the black widow spider Latrodectus 4 hesperus produces high-performance silks with a broad range ofbiological functions and mechanical properties. The cob weaver spider spins different fibers by using seven specialized glands located in its abdomen. Egg …

Generation of A L. Hesperus embryonic cDNA library for the isolation of genes involved in early pattern formation
… body pattern. To enable studies of the Westem black widow spider, Latrodectus hesperus, an embryonic eDNA library and a fixation protocol were developed for L. hesperus embryos. The generation of these tools will allow comprehensive analysis of black widow spider development and give insight …

Part I characterization of MyoR in C2C12 mouse fibroblasts. Part II isolation and characterization of a novel class II bHLH transcription factor from the black widow spider, latrodectus hesperus
… prepared from silk-producing glands of the black widow spider, we have identified a new bHLH transcription factor named BW6. Within the bHLH region, BW6 shows considerable conservation with other HLH proteins, including Drosophila melanogaster achaete and scute, as well as three HLH proteins …

Generation of cDNA chips from the black widow spider, latrodectus hesperus, for gene discovery and expression profiling using microarray technology, and molecular characterization of a novel silk glue protein
… unknown genes from various silk glands of the black widow spider to profile their expression patterns and to identify novel candidates. Spiders are remarkable creatures because of their ability to make different silks, each with a specific function. Some of these silks have amazing mechanical …

Characterization of the large diameter fibers in egg case silk : identification of a core fibroin, TuSp1, and localization of fibroin-like molecules, ECPs, from the black widow spider, latrodectus hesperus
<p>Araneoid spiders use specialized sets of abdominal silk glands to produce up to seven different types of silks, each with diverse functional properties. At the time of these studies, fibroin eDNA sequences that encode egg case silk had not been reported in the literature. This study used …

Characterizing small molecular weight proteins from Latrodectus hesperus dragline and tubuliform silks
<p>Spiders produce a diverse number of silk proteins that are well-known for their extraordinary mechanical and biological properties. Dragline silk has been the most prominent focus of research because of its exceptional high tensile strength and extensibility. In our research, we have focused on …

Identification of an aqueous glue protein, SCP-2, and the development of a polyclonal antiserum against the bHLH transcription factor SGSF in Latrodectus Hesperus
<p>Although numerous spider fibroins have been reported, no known silk coating peptides have been discovered. We provide the first biochemical evidence for a spider coating peptide, called SCP-2, found on gumfooted lines, scaffolding joints and egg cases. The presence of this spider coating peptide …
