Abstract
The present disclosure provides compositions and methods relating to the evaluation of BAFF in a biological sample from a subject.
Claims19
-2. (canceled)
A method of evaluating the distribution of BAFF, the method comprising:
- (a) contacting a first biological sample with a first anti-BAFF antibody, which binds BAFF independent of whether BAFF is bound to a receptor;
- (b) contacting a second biological sample, of the same type as the first, with a second anti-BAFF antibody, which preferentially binds free BAFF over BAFF bound to receptor;
- and
- (c) comparing the binding of the first antibody and the binding of the second antibody in the two samples,
- wherein the comparison in (c) indicates the distribution of BAFF among various physiological pools in the samples.

A method of evaluating a compound or composition for the ability to modulate total BAFF, the method comprising:
- (a) administering a test compound or composition to a mammal;
- (b) obtaining a biological sample from the mammal;
- (c) contacting the sample with an anti-BAFF antibody that binds BAFF independent of whether BAFF is bound to a receptor;
- (d) evaluating the amount of BAFF bound by the antibody in the biological sample;
- and
- (e) comparing the amount of BAFF bound by the antibody in the biological sample with the amount of BAFF bound by the antibody in a control sample,
- wherein a difference in binding attributable to the test compound or composition indicates that the compound or composition is effective in modulating total BAFF in the mammal.

A method of evaluating a compound or composition for the ability to modulate the distribution of BAFF, the method comprising:
- (a) administering a test compound or composition to a mammal;
- (b) obtaining a biological sample from the mammal;
- (c) contacting the sample with a first anti-BAFF antibody, which binds BAFF independent of its physiological state;
- (d) contacting the sample with a second anti-BAFF antibody, which preferentially binds free BAFF over BAFF bound to BAFF receptor;
- (e) detecting binding of the first antibody and the second antibody to BAFF in the sample;
- and
- (f) comparing the binding of the first antibody and the second antibody in the biological sample to the binding of the first and second antibodies in a control sample, wherein a difference in binding attributable to the test compound indicates that the compound or composition is effective in modulating the distribution of BAFF in the mammal.

A method of evaluating a test compound or composition for the ability to modulate the distribution of BAFF, comprising:
- (a) administering a test compound or composition to a mammal;
- (b) obtaining a first biological sample and a second biological sample, both of the same type, from the mammal;
- (c) contacting the first biological sample with a first anti-BAFF antibody, which binds BAFF independent of whether BAFF is bound to a receptor;
- (d) contacting the second biological sample with a second anti-BAFF antibody, which preferentially binds free BAFF over BAFF bound to receptor;
- (e) detecting binding of the first antibody and the second antibody to BAFF in the two biological samples;
- and
- (f) comparing the binding of the first antibody and second antibody in the two biological samples to the binding of the first and second antibodies, respectively, in one or more control samples,
- wherein a difference in binding attributable to the test compound or composition indicates that the compound or composition is effective in modulating the distribution of BAFF in the mammal.
