Product Summary
The Quantikine Mouse Leptin Immunoassay is a 4.5 hour solid phase ELISA designed to measure soluble mouse leptin in cell culture supernates, serum*, and plasma. It contains recombinant mouse leptin expressed in E. coli and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse leptin accurately. Results obtained measuring natural mouse leptin showed dose-response curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse leptin.

*Pregnant mouse serum from the second trimester of pregnancy through post-partum day 1 require acid/urea activation of mouse leptin.

Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: Leptin/OB
Leptin is a product of the mouse obese gene. Mice with mutations in the obese gene that block the synthesis of leptin are obese and diabetic, and have reduced activity, metabolism, and body temperature. Rat leptin shares approximately 96% and 82% sequence identity with the mouse and human protein, respectively. The expression of leptin mRNA is restricted to adipose tissue.
  • Entrez Gene IDs:
    3952 (Human); 16846 (Mouse); 25608 (Rat)
  • Alternate Names:
    FLJ94114; LEP; leptin (murine obesity homolog); leptin (obesity homolog, mouse); Leptin; OB; Obese protein; obese, mouse, homolog of; Obesity factor; OBOBS

FAQs

  1. Why is the acid activation procedure required for pregnant mouse serum samples from second trimester through post-partum day 1 in the Mouse/Rat Leptin Quantikine® ELISA assay?

    • Mouse Leptin R intereferes in the MOB00 assay at high concentration >2000 pg/mL, and studies have shown that there is a massive increase in the level of criculating Leptin Receptor (OB-R) during later stage of pregnancy. Acid activation helps to dissociate the interaction between Leptin and its high affinity recceptor OB-R thus minimizing possible interference in the Leptin assay. Note that activation is not required for samples obtained from non-pregnant mice. Ref. J. Biol. Chem (1997) 272(48):30546-51.
