ELISA Kit Reagents and Accessories

ELISA Blocking Buffer (General) contains a mammalian protein blocking agent suitable for most antibody capture ELISA formats and peptide or protein antigen-down ELISA formats. This blocking buffer provides a long-term stabilizing environment for dried antigen or antibody coat proteins and minimizes nonspecific binding interactions during the assay process.

100 ml/$60; 500 ml/$145

Eliminate interference and nonspecific background noise associated with antibody-coated ELISA formats and sandwich ELISAs. ELISA Blocking Buffer (Background Blocking) provides superior background-blocking performance without the use of conventional cross-reactive protein additives.

ELISA Blocking Buffer (Alkaline Phosphatase) is a novel non-protein blocking formulation designed to eliminate interference and nonspecific background noise associated with antibody-coated ELISA formats and sandwich ELISAs. It is formulated for ELISAs using alkaline phosphatase detection or for assays with ultra-sensitivity requirements. Use of this blocking formulation provides superior background performance without the use of conventional cross-reactive protein additives.

ELISA Blocking Buffer (Non-Mammalian) is designed primarily for antigen-down ELISA formats as well as sandwich assays with high background problems. This buffer is particularly useful when working with human and other mammalian serum samples as it works to reduce interactions between sample and blocking molecules.

100 ml/$66; 500 ml/$185; 1 l/$329

ELISA Blocking Buffer (High Strength) is a high strength blocking buffer designed to address high background problems in antigen-down and sandwich immunoassays. Using a heterogenous mixture of non-mammalian blocking agents, ELISA Blocking Buffer (High Strength) reduces non-specific binding and stabilizes proteins.

100 ml/$64; 500 ml/$146; 1000 ml/$291

ELISA Blocking Buffer (Synthetic) provides superior background-blocking performance to eliminate interference and minimize background noise on ELISA formats without the use of conventional cross-reactive protein additives.
