Antibodies To Surface Igm Can Accelerate Apoptosis Of Mature B-Lymphocytes At Sub - Stimulatory Concentrations, Erica Anderson-Nissen, Robert F. Ashman
Journal of the Minnesota Academy of Science
Antibody to B-cell surface immunoglobulin D (IgD) or surface IgM results in crosslinking of Ig molecules and signal transduction. The function of these surface immunoglobulins has traditionally been investigated by extensive crosslinking experiments and interest has been focused on activation assays. We investigated the effects on apoptosis of culture with anti-(mathematical symbol) antibody (anti-(mathematical symbol)) concentrations ranging from 0.001 (mathematical symbol) mL-1 to 50 (mathematical symbol)g mL-1. Previous experiments have shown that weak dose anti-(mathematical symbol) antibody (anti-(mathematical symbol)) increases mature B-cell apoptosis at both 16- and 64-hour time points, while greater dose anti-(mathematical symbol) results in cell cycle entry …

A cbh1 cellobiohydrolase gene was cloned and sequenced from the fungus Trichoderma harzianum FP108. The cloning was performed by PCR amplification of T. harzianum genomic DNA, using PCR primers whose sequence was based on the cbh1 gene from Trichoderma reesei. The 3' end of the gene was isolated by inverse PCR; attempts to clone regions upstream of the 5' end of the gene were unsuccessful. Sequence comparisons suggest that this gene is closely related to cbb1 genes from other Trichoderma species. In particular, all catalytically important amino acids in the protein sequence deduced from the T harzianum cbb1 gene are …
