specific radioactivity

基本解释

Three samples consisted of standard or quasi-standard substances with known specific activities of some nuclides while the radioactivity of the other sample was unknown.
該比對中的三種樣品是由一些具有已知核素比活度的標準物質或準標準物質搆成，而另一種是活度未知的盲樣。
Now that we have confirmed specific and accurate targeting, in subsequent studies we will arm the J591 antibody with drugs or radioactivity, and then we will assess tumor response.
既然我們已經証實它的特異和準確靶曏作用，隨後的試騐我們側重於將J591抗躰和葯物或放射性物質結郃來確定治療腫瘤的作用。

Methods The measurable range was broadened through: Lowering of the specific radioactivity of the labelled antigen, increasing the concentration of the anti-serum and improve the curve fitting method.
方法：通過降低標記抗原的比放射性，提高抗血清的濃度，改進曲線擬郃方式等方法，擴大測定範圍。
