Abstract
Background
The ability to precisely measure specific mRNA levels by hybridization to complementary DNA probes is an important tool for analyzing the regulation of gene expression. Surfactant proteins have important roles in regulating surfactant metabolism as well as in determining its physical properties.
Methods
The complete coding regions for rat surfactant protein complementary DNA of surfactant protein B were subcloned into pGem 32 or 42 such that either antisense or sense transcripts were obtained by using SP 6 RN A polymerase. Surfactant protein B mRNA was measured by filter hybridization.
Results
Equation of standard cuπe between counts per minute (Y) and surfactant protein B mRNA transcript input (X) was Y=2034.9 X+159. 1. Correlation coefficient was 1. 0.
Conclusions
Filter hybridization assay is suited to situations when rapid, accurate quantitation of multiple samples is required
Key Words: Filter hybridization, Quantitation mRNA, Surfactant Protein B
