Characterization Of Genes Involved In Black Widow Spider Development

open access: yes, 2005
Lactrodectys hesperus, (black widow spiders), are reasonably close relative of the fruit fly, Drosophila melanogaster, yet have very different body plans. The development of the fly has proven to be similar in most animals, including us.

In-Depth Proteome Analysis of Black Widow Dragline Spider Silk

open access: yes, 2016
Spider silk in Lactrodectus hesperus (black widow spider) species is renowned for its tensile strength, toughness and elasticity. These properties allow spider silk to outperform some of the best man-made materials such as Kevlar.

Identification of Novel cDNAs that Code for Spider Silk in Black Widow Spiders

open access: yes, 2010
Latrodectus hesperus produces silk with high tensile strength and extensibility. This allows it to be up to five times stronger than steel, when compared on a weight-to-strength basis.

Hunting for new spider silk genes in the black widow spider, Latrodectus hesperus

open access: yes, 2009
Spider silk has the potential to be used in many applications such as sutures, fishing nets, body armor and drug delivery systems. The purpose of the study was to find new silk genes by screening a cDNA library that was constructed from the silk ...
