Mouse anti Human Complement Factor B (Ba Fragment) antibody, clone 014III-22.214.171.124
recognises the 30 kDa Ba fragment of 90 kDa human complement factor B, present in blood serum. C3b associates with complement factor B, inducing conformational change. This enables complement factor D to cleave the N-terminal of complement factor B (the Ba subunit), leaving the 63 kDa Bb subunit associated with C3b, forming C3 convertase. Subunit Ba inhibits lymphocyte proliferation. Conversely, subunit Bb is involved in the proliferation of preactivated B lymphocytes.
Mouse anti Human Complement Factor B (Ba Fragment) antibody, clone 014III-126.96.36.199 has been reported for use in functional studies to block activity of the target protein. Removal of Sodium Azide is recommended prior to use in functional assays. Bio-Rad recommend the use of EQU003
for this purpose.
