Description
Specificity:
Goat Anti-Human Leptin recognizes Human Leptin. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.
Background:
Leptin is a neuroendocrine hormone secreted from adipose tissue that plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism. Leptin is one of the most important adipose derived hormones.1 It interacts with six types of receptors and once it binds to OB-Receptor it activates the stat3, which is phosphorylated and travels to the nucleus to effect changes in gene expression. One of the main effects on gene expression is the down-regulation of the expression of endocannabinoids.2 High leptin levels are associated with psoriasis.3
Immunogen
E. coli-Derived Recombinant Human Leptin
Formulation
This biotinylated antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 50 µg of bovine serum albumin per µg of antibody with no calcium, magnesium, or preservatives present.
Reconstitution
We suggest aseptically reconstituting this biotinylated, lyophilized, antigen affinity purified polyclonal antibody with 1 ml of sterile 20 mM Trizma base, 0.15 M sodium chloride (1X Tris Buffered Saline) pH 7.2-7.3, containing 0.1% w/v bovine serum albumin (BSA). This will result in a final biotinylated antibody concentration of 50 µg/ml.
Storage and Stability
The lyophilized, biotinylated antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for up to twelve months from date of receipt. The reconstituted bioin conjugate can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted conjugate, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.
Reported Applications
WB
Western Blotting: To detect Human Leptin this biotin conjugate can be used at a concentration of 0.1 - 0.2 µg/ml. This biotin conjugate should be used in conjunction with compatible second-step reagents such as UltraAvidin™- Horseradish Peroxidase (HRPO) (Leinco Prod. No.: A106) and a chromogenic substrate such as TMB HRPO Membrane/IHC Substrate UltraSensitive™ One Component "Ready Use" (Leinco Prod. No.: T343). The detection limit for Human Leptin is 5 ng/lane under either reducing or non-reducing conditions. The sensitivity of detection may increase up to 50 fold when a chemiluminescent substrate is used.
