The skin of Xenopus laevis contains a soluble beta-galactoside-binding lectin with a approximately 16,000-mol-wt subunit. It resembles similar lectins purified from a variety of tissues from other vertebrates, and differs from two other soluble X. laevis lectins from oocytes and serum that bind alpha-galactosides. The skin lectin is concentrated in the cytoplasm of granular gland and mucous gland cells, as demonstrated by immunohistochemistry with the electron microscope. Upon injection with epinephrine, there is massive secretion of the cytoplasmic lectin from the granular gland cells.
非洲爪蟾的皮肤含有一种可溶性β-半乳糖苷结合凝集素,其亚基分子量约为16,000。它类似于从其他脊椎动物的多种组织中纯化得到的类似凝集素,并且不同于从卵母细胞和血清中分离得到的另外两种结合α-半乳糖苷的非洲爪蟾可溶性凝集素。通过电子显微镜免疫组织化学证明,皮肤凝集素集中在颗粒腺和黏液腺细胞的细胞质中。注射肾上腺素后,颗粒腺细胞的细胞质凝集素会大量分泌。
