RIPA lysis buffer composition

I am currently following a protocol that uses a buffer termed RIPA 
lysis buffer.  The buffer is currently being used in the preparation of 
conceptus homogenates which are subsequently assayed for DNA content and 
protein concentrations.  I have a suspicion that our recipe for this buffer 
is incorrect.  Does anyone know if this is a commonly used buffer?  If so, 
what is its composition? Specifically, the problem appears to be the Triton-
X 100 concentration of the buffer which interfers dramatically with our DNA 
fluorometric assay.  Any comments or suggestions are welcomed.
