Background of SFTPA2
SFTPA1/2 is also known as SP-A. SFTPA1 encodes a lung surfactant protein that is a member of a subfamily of C-type lectins called collectins. The encoded protein binds specific carbohydrate moieties found on lipids and on the surface of microorganisms. This protein plays an essential role in surfactant homeostasis and in the defense against respiratory pathogens. Mutations in this gene are associated with idiopathic pulmonary fibrosis. Alternate splicing results in multiple transcript variants. SFTPA2 is one of several genes encoding pulmonary-surfactant associated proteins (SFTPA) located on chromosome 10. Mutations in this gene and a highly similar gene located nearby, which affect the highly conserved carbohydrate recognition domain, are associated with idiopathic pulmonary fibrosis. The current version of the assembly displays only a single centromeric SFTPA gene pair rather than the two gene pairs shown in the previous assembly which were thought to have resulted from a duplication.

Figure 1. Western blot analysis of SFTPA1/2 using anti-SFTPA1/2 antibody (PB9390).
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 30 ug of sample under reducing conditions.
Lane 1: rat lung tissue lysates,
Lane 2: mouse lung tissue lysates.
After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA 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-SFTPA1/2 antigen affinity purified polyclonal antibody (Catalog # PB9390) at 0.5 μg/mL overnight at 4°C, 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 1:5000 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 SFTPA1/2 at approximately 26-38 kDa. The expected band size for SFTPA1/2 is at 26 kDa.

Question
We are currently using anti-SFTPA1/2 antibody PB9390 for human tissue, and we are well pleased with the WB results. The species of reactivity given in the datasheet says human, mouse, rat. Is it possible that the antibody can work on horse tissues as well?

Answer
The anti-SFTPA1/2 antibody (PB9390) has not been tested for cross reactivity specifically with horse tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in horse you can get your next antibody for free. Please contact me if I can help you with anything.
