Neptune™ HRP Conjugate Stabilizer preserves the activity of HRP-protein conjugates. This HRP stabilizer can be used to store concentrated stock HRP conjugates, reconstitute lyophilized conjugates, and dilute HRP conjugated antibodies to their useful working titer in ELISA tests and immunology-based techniques.Neptune™ HRP Conjugate Stabilizer is especially suited for ELISAs using anti-IgG HRP conjugates within traditional ant…

General Block contains a mammalian protein blocking agent suitable for most antibody capture ELISA formats and peptide or protein antigen-down ELISA formats. General Block contains a mammalian protein blocking agent designed to reduce nonspecific background noise in most antibody capture ELISA formats and peptide/protein antigen-down ELISA formats. This unique, low-level blocking buffer minimizes nonspecific binding interacti…

Neptune Block Blocking Buffer is designed primarily for antigen-down ELISA formats as well as sandwich assays with high background problems. Neptune Block ELISA Blocking Buffer is particularly useful when working with human and other mammalian serum samples as it works to reduce interactions between sample and blocking molecules.Neptune Block ELISA Blocking Buffer is a mixture of small molecular proteins and molecular stabili…

Eliminate interference and nonspecific background noise associated with antibody-coated ELISA formats and sandwich ELISAs. SynBlock ELISA Blocking Buffer provides superior background-blocking performance without the use of conventional cross-reactive protein additives. SynBlock ELISA Blocking Buffer is a novel non-protein blocking formulation designed to eliminate interference and nonspecific background noise associated with…

Phosph-Free Block ELISA Blocking Buffer is a novel non-protein blocking formulation designed to eliminate interference and nonspecific background noise associated with antibody-coated ELISA formats and sandwich ELISAs.Phosph-Free Block is formulated for ELISAs using alkaline phosphatase detection or for assays with ultra-sensitivity requirements. However, it is appropriate for assays using HRP detection as well. Using inert no…

Reduce non specific binding in ELISAs and stabilize proteins with Alternative Block, an all-synthetic ELISA blocking buffer free of proteins and detergents. Alternative Block is a protein-free, detergent-free ELISA blocking buffer. This unique blocking buffer contains a heterogeneous mixture of proprietary blockers and synthetic stabilizers that block the uncoated regions of the microtiter plate without the use of conventiona…

Reduce non specific binding in ELISAs, address high background issues, and stabilize proteins with Monster Block, a new ELISA blocking buffer utilizing a heterogenous mixture of nonmammalian blocking agents. Monster Block™ provides a high degree of blocking efficiency and protein stabilization through the use of non-mammalian protein blocking agents and stabilizers. The heterogeneous composition of this unique ELISA blocking…

Detect caspase-1 activity with the FLICA® Caspase 1 Assay Kit. This in vitro assay employs the green fluorescent inhibitor probe FAM-YVAD-FMK to label active caspase 1 enzyme in living cells or tissue samples. Analyze the fluorescent signal using fluorescence microscopy, a fluorescent plate reader, or by flow cytometry. Caspase 1 (ICE):Members of the mammalian caspase family of cysteinyl aspartate-specific proteases play disti…

Magic Red™ Caspase 3 and 7 Assay is a substrate-based fluorescent apoptosis assay that measures DEVDase enzyme activity in living, intact cells. Detection of caspase 3 and 7 activity (DEVDase enzymes) is a reliable method for assessing apoptotic activity in experimental cell populations. The Magic Red™ caspase 3 and 7 fluorogenic substrate, MR-(DEVD)2, is primarily targeted by caspases 3 and 7 of the apoptotic protease casca…
