Streptococcus pneumoniae are Gram positive, lancet shaped cocci (elongated cocci with a slightly pointed outer curvature). They are a major human pathogen that cause lung infections that often develop as secondary infections into other respiratory disorders such as bronchial pneumonia. Applications: Suitable for use in Immunofluorescence. Other applications not tested. Recommended Dilution: Immunofluorescence: 1:10-1:50. Acetone fixation of the antigen source is recommended prior to staining. Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20C. Aliquots are stable at -20C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
