Imunohistokemijsko istraživanje raspodjele kalbindina-D28k u bubregu kune bjelice (Martes foina)

The localization of approximately 28,000 relative molecular mass with calcium-binding protein (calbindin-D28k) was investigated in the kidney of beech marten (Martes foina Erxleben, 1777). Positive cells for calbindin-D28k were found in the distal tubule by the immunohistochemical ABC technique. No reaction was seen in the proximal tubules, loops of Henle and glomeruli. Calbindin-D28k plays a significant role in calcium reabsorption in the distal convoluted tubule of kidney.
Nalaz proteina vezanog na kalcij (kalbindina-D28k) relativne molekularne mase 28000 istražen je u tkivu bubrega kune bjelice (Martes foina Erxleben, 1777). Stanice pozitivne na kalbindin-D28k dokazane su u distalnim tubulima imunohistokemijskim postupkom. Reakcija nije ustanovljena u proksimalnim tubulima, Henleovoj petlji i glomerulima. Kalbindin-D28k ima važnu ulogu u reapsorpciji kalcija u distalnim bubrežnim tubulima.
