IPKine™ HRP Goat Anti-Mouse IgG HCS: Eliminating Light Chain Interference in IP-Western Blot
The 25 kDa Ghost Band In IP-WB, the IgG light chain (≈25 kDa) creates a persistent band that can obscure target proteins migrating at that molecular weight. If your protein of interest runs at 25 kDa, this artifact has likely been inflating your protein interaction data. Abbkine's IPKine™ HRP Goat Anti-Mouse IgG HCS (A25112) solves this problem. It binds exclusively to the Fc region of the 50 kDa heavy chain, leaving the 25 kDa region completely dark. Any band you detect at 25 kDa is your protein—not your antibody. Heavy Chain Specificity (HCS) for Clean 25 kDa Detection A25112 is heavy chain specific (HCS) —it recognizes only the heavy chain of mouse IgG, not the light chain. This specificity ensures that the 25 kDa region remains…
IPKine™ HRP Mouse Anti-Rabbit IgG LCS: The Monoclonal Solution to Heavy Chain Interference
The Heavy Chain Problem, Solved When performing IP-WB with rabbit primary antibodies, the IgG heavy chain (≈50 kDa) routinely generates a false band that obscures target proteins migrating in that molecular weight range. "Most anti-rabbit IgG secondaries bind both heavy and light chains of the primary antibody, and when you're using a rabbit-derived primary in IP, that heavy chain cross-reactivity turns your WB into a guessing game". Abbkine's IPKine™ HRP Mouse Anti-Rabbit IgG LCS (A25022) is a monoclonal antibody that binds exclusively to the light chain of rabbit IgG (≈25 kDa). The 50 kDa region remains completely clean. Monoclonal Precision A25022 is a mouse monoclonal antibody purified to >95% purity by SDS-PAGE. Every antibody molecule recognizes the same epitope with identical affinity, eliminating the lot-to-lot epitope distribution drift…
IPKine™ HRP Goat Anti-Mouse IgG LCS: Eliminating Heavy Chain Interference in IP-Western Blot
The 50 kDa Band That Was Never Your Protein If you've ever performed immunoprecipitation followed by Western blot (IP-WB), you know the frustration: a prominent band at ~50 kDa that isn't your target protein. That band is the IgG heavy chain—and it has been hijacking your blots for decades. Abbkine's IPKine™ HRP Goat Anti-Mouse IgG LCS (A25012) solves this problem at the source. It binds exclusively to the light chain of mouse IgG (≈25 kDa), leaving the 50 kDa heavy chain region completely dark. The Light Chain Specificity Advantage Traditional secondary antibodies recognize both heavy and light chains, creating two bands (25 kDa and 50 kDa) that obscure target proteins. A25012 is light chain specific (LCS) —it recognizes only the light chain fragment at 25 kDa. The 50…
