Gene Information

General description

Pulmonary surfactant is a complex mixture of phospholipids and proteins secreted from airway epithelial cells (type II cells) in alveoli which reduces the surface tension at the alveolar air liquid interface, providing alveolar stability necessary for normal ventilation. Four distinct proteins isolated from pulmonary surfactant are termed surfactant proteins A, B, C and D. SP A (28 - 36 kDa) and SP D (43 kDa) are collagenous carbohydrate binding proteins, whereas SP B (8 - 9 kDa) and SP C (4 kDa) are non collagenous hydrophobic proteins. SP C is a fragment of a much larger precursor protein of 21 kDa. The precursor contains an exceedingly hydrophobic region of 34 amino acids that comprises most of the mature SP C, and a unique poly-valine domain.


Expected to cross-react with human.
Reacts strongly with proSP-C from human and mouse. Immunoprecipitates the 21 kDa proprotein as well as processing intermediates of M.W. 26 kDa, 21 kDa, 16 kDa and 14 kDa. Preincubation of the antiserum with the fusion protein results in ablation of immunostaining. On human tissue immunostains alveolar Type II cells in normal lung. The antibody also recognizes the aberrant form of proSP-C (6-12 kDa peptide) found in BAL and in alveolar proteinosis material on sections of lung samples from human patients with hereditary SP-B deficiency. On mouse tissue immunostains alveolar Type II cells in normal lung.


A synthetic peptide corresponding to amino acids 1-32 from the N-terminal of the human SP-C proprotein coupled to KLH


Anti-Prosurfactant Protein C (proSP-C) Antibody detects level of Prosurfactant Protein C (proSP-C) and has been published & validated for use in ELISA, Immunohistochemistry (IHC), Immunohistochemistry - Paraffin (IHC-P) and Western Blotting (WB).
1:2,000-1:4,000 dilution of a previous lot was used on human tissue (see protocol), 1:4,000 dilution on adult mouse lung and 1:1,000-1:2,000 dilution on fetal mouse lung (see protocol).
Immunohistochemistry: 1:2,000-1:4,000 on human tissue with and without antigen retrieval (see protocol) and 1:1,000-1:2,000 on adult and 1:500-1:1,000 on fetal mouse lung (see notes).

1:5,000 (best if not reduced)

Western Blot Analysis:
a previous lot used a dilution of 1:500


1) Dilutions used are for normal (i.e. uninjured) adult mouse lung and have been used on FVB/N, Balb/c, nu/nu and SCID mice. The use of antigen retrieval systems to enhance immunostaining for this antibody is not necessary in the mouse lung and may actually increase background staining.

Optimal dilutions must be determined by the end user.
