Theoretical and experimental values of the critical volume fraction, ϕ_c

	ϕc
Spherical particles with very long range of interactions	0.13*
Spherical particles with very short range of interactions	0.27*
Human lens γD crystallin	0.13†
Chicken egg white lysozyme	0.16‡
Bovine lens γ crystallins (including γB, γC, γD, γE )	0.21§
Immunoglobulins: (IgG2-A, IgG2¶, IgG1∥)	0.063

The values are taken from refs. 14, 16, 24, and 18. The value listed for (IgG2-A) is taken from Fig. 1 and is consistent with data reported for other immunogolobulins in refs. 6 and 7.
