应用 Ab评论 说明
WB 1/500 - 1/1000. Detects a band of approximately 22 kDa (predicted molecular weight: 22 kDa).

IHC-P 1/50 - 1/100.


  • 功能
    Involved in transport from the endoplasmic reticulum to the Golgi apparatus. Activated by the guanine nucleotide exchange factor PREB. Involved in the selection of the protein cargo and the assembly of the COPII coat complex.
  • 组织特异性
    Expressed in many tissues including small intestine, liver, muscle and brain.
  • 疾病相关
    Defects in SAR1B are the cause of chylomicron retention disease (CMRD) [MIM:246700]; also known as Anderson disease (ANDD). CMRD is an autosomal recessive disorder of severe fat malabsorption associated with failure to thrive in infancy. The condition is characterized by deficiency of fat-soluble vitamins, low blood cholesterol levels, and a selective absence of chylomicrons from blood. Affected individuals accumulate chylomicron-like particles in membrane-bound compartments of enterocytes, which contain large cytosolic lipid droplets.
  • 序列相似性
    Belongs to the small GTPase superfamily. SAR1 family.
  • 细胞定位
    Endoplasmic reticulum membrane. Golgi apparatus > Golgi stack membrane. Associated with the endoplasmic reticulum and Golgi stacks, in particular in the juxta-nuclear Golgi region.

Merci pour votre appel de hier.

Je peux vous confirmer que nos deux anticorps contre le SAR1B ne vont pas crossréagir avec le SAR1A. Ceci n'a pas spécifiquement été testé à ma connaissance, mais les i...
