25x Biotin-detection Ab (human Resistin Biotin-dAb). PN: B111203B. One vial containing 100 µL of biotinylated anti-humanResistin.

Lyophilized Standard Mix-Human Group 4 Panel B, 10-Plex. PN: HG40010. One vial containing lyophilized recombinant human GASP-1, IFNβ, ANGPT-1, Insulin, Leptin, MIF, Resistin, Survivin, TGFα, and TPO. Note: If multiple analyte kits on the above target list are ordered as a panel, only one vial of standard mix is supplied for those analyte kits.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Application: Optimal antibody pair and antigen standard for assaying human Resistin.  Can be multiplexed with other analytes in Human Group 4.  To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Description:

Resistin, also known as adipose tissue-specific secretory factor (ADSF) or C/EBP-epsilon-regulated myeloid-specific secreted cysteine-rich protein (XCP1) is a cysteine-rich adipose-derived peptide hormone. In primates, pigs, and dogs, resistin is secreted by immune and epithelial cells, while, in rodents, it is secreted by adipose tissue. Resistin is an adipose-derived hormone (similar to a cytokine) whose physiologic role has been the subject of much controversy regarding its involvement with obesity and type II diabetes mellitus (T2DM). Resistin has been shown to cause "high levels of 'bad' low-density lipoprotein or LDL cholesterol, increasing the risk of heart disease, increases the production of LDL in human liver cells and also degrades LDL receptors in the liver. As a result, the liver is less able to clear 'bad' cholesterol from the body. Resistin accelerates the accumulation of LDL in arteries, increasing the risk of heart disease and adversely impacts the effects of statins, the main cholesterol-reducing drug used in the treatment and prevention of cardiovascular disease. Diseases associated with resistin include acquired generalized lipodystrophy and end-stage renal failure.
