无封闭ELISA试剂产品是Enzyme-linked immunosorbent assay (ELISA) is widely used to measure the concentration of various analytes in biological samples. Howevernthis assay can be time consuming as it involves multiple steps including coatingnblockingnantigen/antibody binding incubationnas well as washing between each step. Among all proceduresnblocking step is very important to reduce non-specific binding and improve signal/noise (S/N) ratio. BioVision’s Block-Free ELISA Reagent is a superior primary and secondary antibody diluentneliminating the blocking step and saving time while ensuring low background. This reagent contains 1% BSA. For the customer who wants to avoid use of BSAnthe Protein free version (BV M4101) is recommended.
