Antibodies for Aging Research

Anti SMP30 [Regucalcin,Gluconolactonase(GNL)] polyclonal antibody


SMP30 (Senescence Marker Protein-30) is a 34-kDa protein whose tissue levels in the liver, kidney, and lung decrease with aging (1, 2). SMP30 expressed in multiple tissues including the liver, kidney, brain, lung, adrenal gland, stomach, ovary, uterus, testis and epidermis. Recently, SMP30 was identified as the lactone-hydrolyzing enzyme gluconolactonases (GNL) of animal species (3). GNL is a key enzyme which involve in vitamin C (L-ascorbic acid) biosynthesis. SMP30 knockout mice displayed symptoms of scurvy when fed a vitamin C-deficient diet. Moreover, SMP30 protects mice lungs from oxidative stress associated with aging and smoking (4). Thus SMP30 is a key age-associated protein for aging, vitamin C and lung disease research.
SMP30, Gluconolactonase and Regucalcin are all identical protein.

Immunohistochemical staining

Mouse liver stained with SMP30・GNL antibody at 1:300 dilution and developed by 3,3’-diaminobenzidine. Nucleus and cytoplasm of wild ype (SMP30+/+) mice stained, but not stained in liver from SMP30 knockout (SMP30-/-) mice.

Western Blot Analysis

Each lanes: Mouse Liver Extract
Wild type Mouse : SMP30Y/+ and SMP30+/+
SMP30 Knockout Mouse : SMP30Y/- and SMP30-/-
Heterozygous Mouse : SMP30+/-
SMP30・GNL antibody at 1:1,000 dilution used.

Immunofluorescence staining

Primary cultured mouse hepatocytes stained with SMP30・GNL antibody at 1:200 dilution. Nucleus and cytoplasm stained in green.
