Selecting life: Scientists find new way to search for origin of life

... during the Archean Era when life first emerged. In 2001 Hazen and colleagues performed the first experiments showing that the left-handed amino acid, aspartic acid, preferentially adhere to left-faced calcite. That study confirmed previous theoretical suggestions of a plausible process by which the mixed rig...

Engineers improve plastic's potential for use in implants by linking it to biological material

...dition, they determined that a certain amino acid, aspartic acid, had to be a part of T59 for it to attach well to the plastic. aspartic acid carries a negative charge, which in T59 appea...rges cling together. Yet other peptides containing aspartic acid didn't attach to polypyrrole, leading the res...

ISOQUANT Isoaspartate Detection Kit from Promega

Description:...n of isoaspartic acid residues in proteins and peptides, which can result from the gradual, nonenzymatic deamidation of asparagine or rearrangement of aspartic acid residues during storage or handling. Because the kit does not depend on the monitoring of charge differences for detection, charge heterogeneity ...

Anion Exchange ProteinChip Arrays from Ciphergen

Description:...d characterize proteins directly on the chip. Anionic arrays bind proteins through electrostatic interaction of negatively charged amino acids such as aspartic acid and glutamic acid. Binding occurs at high pH with low salt and binding decreases as pH decreases and salt concentration increases. ProteinChip SA...
