A: Rotary shadowing electron microscopy images of CS2-G3. The images appear as a globular domain (G3) with an attached extended tail (CS2). The bar represents 100 nm. B: The total molecular length distribution indicates a mean molecular length of 57 ± 5.2 nm for the globular domain and the tail and is suggests a contour length of 48 ± 4.4 nm for CS2 (the tail) with a mass per length of 802 Da nm−1.
