Protein-Free Blocking Buffer & Antibody Dilution Buffer for WB

The Beyotime QuickBlock™ series is the latest generation of efficient and low-background WB products, with performance significantly superior to traditional blocking buffers with BSA and many other similar products. Its main features are low background, strong signal, fast and efficient, requiring only 5-15 minutes for blocking.

Beyotime has newly released animal origin-free (AOF) QuickBlock™ Protein-Free Blocking Buffer for Western Blot and QuickBlock™ Protein-Free Primary/Secondary Antibody Dilution Buffer for Western Blot, effectively avoiding potential interactions with protein samples, thereby improving the specificity of protein assay.

Product Features
●   Free of protein and animal origin: effectively avoiding potential interactions with protein samples, thereby improving the accuracy of protein detection.
●   Fast, efficient, and antibody saving: The QuickBlock™ Protein-Free Blocking Buffer for Western Blot only requires 5-10 minutes for the blocking, similar to QuickBlock™ Western Blocking Buffer (Beyotime, P0252), but significantly faster than 5% BSA. Primary antibodies diluted and prepared with QuickBlock™ Protein-Free Primary/Secondary Antibody Dilution Buffer for Western Blot can be stored at 4℃ for at least 1 month and can be reused multiple times. The diluted secondary antibodies in this buffer can be reused 3-5 times within 2-3 weeks, effectively saving antibodies.
●   Low background: This series of products does not contain any protein components and, in principle, does not cross-react with antibodies, improving the assay specificity, leading to clearer Western blot bands, fewer nonspecific bands, extremely low background, and a higher signal-to-noise ratio.
●   Wide applications: Without alkaline phosphatase, casein, and biotin components, this series of products is particularly suitable for the detection of protein modifications such as phosphorylation and glycosylation, as well as biotin detection.
●   Good compatibility: Compatible with secondary antibodies conjugated with horseradish peroxidase (HRP), alkaline phosphatase (AP), and biotin.
●   Convenient to use: These products can be used directly, without the need for additional reagents.
●   High stability: These products are not prone to microbial contamination, and can be stably stored at room temperature for a long time.
