Figure 4. rhIL-2 remains structurally intact after a lasting exposure to near-isosmotic buffered CDHP.

Figure 4

Sandwich ELISA measurements of rhIL-2 concentrations incubated 24 hours (white bars) and 48 hours (black bars) in 30–60mM CDHP (upper panel), or CDHP in NaHCO3 (pH≥7.2) (lower panel). Data are expressed as mean relative rhIL-2 concentrations ±SEM, normalized to the initial amount (T0) of protein (n=6).
