S Tag Peptide: Practical Fusion-Tag Workflow
2026-09-13
S Tag Peptide supports recombinant protein detection, antibody-based capture, and protein solubility improvement when its 15-amino-acid sequence is genetically fused to a target protein. It is suitable for N- or C-terminal fusion workflows, but not for ethanol-based handling, long-term aqueous storage, or experiments that assume the tag is an independently active enzyme.

SPRTN Ubiquitin Binding Enables Rapid DPC Proteolysis
2026-09-12
The reference preprint identifies a ubiquitin-binding region within the N-terminal catalytic domain of SPRTN, showing how ubiquitination directs this protease toward DNA-protein crosslinks (DPCs). Its central result is that ubiquitin-chain engagement increases SPRTN proteolysis of polyubiquitinated DPCs by approximately 67-fold relative to unmodified lesions, providing a mechanistic explanation for rapid substrate selection.

HyperFluor 488 Goat Anti-Rabbit IgG Guide
2026-09-09
HyperFluor™ 488 Goat Anti-Rabbit IgG (H+L) Antibody provides fluorescent detection of rabbit IgG primary antibodies in immunofluorescence, immunohistochemistry, immunocytochemistry, microscopy, and flow cytometry workflows. It should be used with rabbit primary antibodies and assay conditions compatible with its glycerol, BSA, and sodium azide-containing buffer, not as a universal secondary for non-rabbit or enzyme-based detection systems.
