Block Ace powder以乳蛋白为原料制备而成，是一种新型的免疫实验阻断剂。 由于乳蛋白中包含许多疏水基团，因此它对塑料和膜过滤器具有很高的亲和力。
● 与BSA溶液相比，Block Ace是经济的；
Four (4) grams of Block Ace powder is dissolved into 100 mL of purified water, and this solution is used as a concentrate.
For blocking purpose, either concentrate or 2-4× diluted solution with purified water is used (4× diluted solution is used for ELISA; concentrate is used for Western Blotting).
For dilution of samples and labelled antibody, it is diluted to 10× with purified water.
For washing operation such as B/F separation, it is diluted to 10× with purified water, and the required volume of Tween 20 (0.05%–0.2%) is added.
Room temperature (it is cold transported)
(This product is heat treated, but there is no preservative or antibiotic. Once dissolved, it should be frozen before storage)
Anti-human kappa chain antibody and anti-human ramda chain are coated, and it is blocked with either Block Ace or 1% BSA. Human IgG ELISA demonstrates that Block Ace has low background and a steep standard curve.
