MACH 4 is a highly sensitive universal detection system. The MACH 4 system can detect either mouse or rabbit antibodies, and is a two-step universal detection method. MACH 4 is available in a universal (anti-mouse and anti-rabbit) format, labeled with either Horseradish Peroxidase (HRP) or Alkaline Phosphatase (AP). MACH 4 detection consists of two reagents: the secondary, also known as the enhancing reagent, is applied between the primary antibody and micro-polymer reagent. MACH 4 is ideal for use with antibody solutions prepared from concentrates or prediluted antibody solutions. Due to its increased sensitivity, MACH 4 enables a significantly higher dilution of concentrated antibodies compared to other polymer-based detection systems.
MACH 4 micro-polymer system incorporates two key technologies:
- Enhanced probe to increase sensitivity 10- to 20- fold
- Increased density of enzymes bound to tertiaries
- 10 – 20 times more sensitive than conventional dextran polymer systems
- 20 – 40 times more sensitive for nuclear staining
- Suitable to detect mouse specific anti-biotin or antidigoxigenin antibody in in situ hybridization (ISH)
- Micro-polymer allows superior specificity/sensitivity, nuclear access and primary antibody dilution
- Compatible with automated immunostainers
- Compact structure enables 40-fold increase in primary antibody dilution.
