Figure 1.
Images of the hydrogel solution and the LysP53 hydrogel solution containing crystal violet at (A) room temperature (flowable solution) and (B) 32 °C (rigid gel). The SEM micrographs of the Poloxamer 407 hydrogel (C) and LysP53-loaded Poloxamer 407 hydrogel (D). The addition of LysP53 does not affect the three-dimensional structure of the poloxamer 407 hydrogel. A and B are microtubes lying horizontally.
