l for the elucidation of its biological functions. Here we describe the expression and purification of recombinant PTX3. An arginine-containing buffer is essential for the elution of bacterially expressed PTX3 N-terminal domain to minimize aggregation. This method allows high-yield purification of f

,Pappus’s Two General Propositions and Euclid’s First Porism,0–16, 19), the second general Proposition (Proposition 21), Euclid’s first Porism (Proposition 23) and various applications and extensions of these results. Pappus’s Lemmas 1–9 for the Porisms are developed in the course of this Part (see Appendix 3).
