Anti-Surfactant Protein D Antibody, lectin domain, clone IVF11

Surfactant protein D is a Ca2+ dependent carbohydrate binding protein with a structure similar to other C-type mammalian lectins. Its molecular weight is 620 kDa under non-reducing conditions and 43 kDa under reducing conditions. The function of SP-D is not clearly defined. SP-D enhances the production of oxygen radicals in alveolar macrophages and regulates some actions of SP-A.

Epitope: lectin domain

Purified rat surfactant protein D from bronchoalveolar lavage.

Immunohistochemistry on snap frozen or paraffin embedded tissue.

Suggested working dilution for fresh rat tissue is 1:400 and for fresh human tissue is 1:20. Fixation: acetone 5 min at 4°C, paraformaldehyde, paraffin. Tissue pretreatment: microwave treatment 2 x 5 min at 750 W for paraffin tissues.

Western blot

ELISA: as capture antibody

Optimal working dilutions must be determined by the end user.

This Anti-Surfactant Protein D Antibody, lectin domain, clone IVF11 is validated for use in ELISA, IH(P), WB for the detection of Surfactant Protein D.

MAB3132 recognizes an epitope localized in the lectin domain of rat surfactant protein D (SP-D). Reacts with alveolar type II cells, alveolar macrophages, types of Clara cells (in which SpD is highly concentrated), SP-A+ and SP-A-, and extracellular deposits. Alveolar type III cells are negative. No reaction on rat skin, colon, kidney or liver. SP-A cross reacitivity is typically evident at very low dilutions (1 to less than a few hundred) by ELISA.

Format: Purified

Immunoglobulin purified from tissue culture supernatant. Lyophilized from buffer containing 5 mg/mL BSA and 0.09% sodium azide.

Maintain lyophilized material at 2-8°C for up to 12 months from date of receipt. Reconstitute lyophilized material with 500 μL of sterile distilled water. After reconstitution, maintain at -20°C in undiluted aliquots for up to 6 months. Avoid repeated freeze/thaw cycles.
