Antibodies containing "4C" or "4CL" in their identifiers are reviewed here for contextual relevance:
Target: Huntingtin protein (associated with Huntington’s disease) .
Epitope: Mapped to amino acids 443–457 of human huntingtin, with critical glutamic acid residues at positions 443–445 .
Applications:
Commercial Availability: Sold by Merck Millipore (MAB2166) and Thermo Fisher (MA3-040) .
Role: Detection of Aβ aggregates in Alzheimer’s disease research.
Conjugate: SULFO-TAG™ for electrochemical luminescence assays .
Function: Detects both wild-type and mutant huntingtin, aiding in Huntington’s disease (HD) research .
Key Finding: N-terminal fragments of mutant huntingtin are cytotoxic, and 1HU-4C8 helps quantify these fragments in preclinical models .
Utility: Critical for identifying Neisseria strains in meningitis and gonorrhea diagnostics .
Specificity: Binds to heat-killed gonococcal strain 4505 cells with high affinity .
If "4CLL8" refers to an antibody targeting CCR8 (a chemokine receptor implicated in cancer immunotherapy), recent studies describe bispecific antibodies like 2MW4691 (CCR8/CTLA-4) with the following properties :
