Background of Leptin/OB
Leptin have been found to be obese and diabetic and to have reduced activity, metabolism and body temperature. cDNA clones encoding Leptin have been isolated from human, simian, mouse, and rat cells. The expression of Leptin mRNA has been shown to be restricted to adipose tissue. Although regulation of fat stores is deemed to be the primary function of leptin, it also plays a role in other physiological processes, as evidenced by its multiple sites of synthesis other than fat cells, and the multiple cell types beside hypothalamic cells that have leptin receptors. Many of these additional functions are yet to be defined.
Antibody Validation

Figure 1. Western blot analysis of Leptin using anti-Leptin antibody (A00479-4).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 50ug of sample under reducing conditions.
Lane 1: mouse small intestine tissue lysates,
Lane 2: mouse kidney tissue lysates,
Lane 3: mouse Neuro-2a whole cell lysates.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA for 50-90 minutes. Blocked the membrane with 5% Non-fat Milk/ TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-Leptin antigen affinity purified polyclonal antibody (Catalog # A00479-4) at 0.5 μg/mL overnight at 4℃, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Leptin at approximately 23KD. The expected band size for Leptin is at 18KD.

Question
Can you help my question with product A00479-4, anti-Leptin antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?
Verified Customer
Verified customer
Asked: 2019-11-25
Answer
We suggest not storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free A00479-4 anti-Leptin antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Question
Does A00479-4 anti-Leptin antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
Verified Customer
Verified customer
Asked: 2017-10-09
Answer
As indicated on the product datasheet, A00479-4 anti-Leptin antibody as been tested on ELISA. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.
