WebThere are two kinds of tests that are used to determine if a person has been infected with TB bacteria: the TB blood test and the TB skin test. TB blood tests (sometimes called IGRAs) use a blood sample to find TB infection. The tests measure the response of TB proteins when they are mixed with a small amount of blood. WebSo the purpose of the blocking step is to reduce the amount of background due to non-specific bonding. Now, BSA is only made up of one protein, BSA at 60 kDa, whereas milk is made up of many proteins, all of various sizes. So you get a much better chance to reduce more of the background banding. We recommend that you use 5% milk in TBST, shaken ...
