Fibrillin 1 is an extracellular acidic protein with a high cysteine content and an extended thread-like shape with mosaic composition of different types of extracellular modules. Most of the fibrillin molecule is contributed by 47 epidermal growth factor-like (EGF-like) repeats; 43 of them have a consensus sequence for calcium binding (cb). Other modules including 8-cysteine motifs (seven), hybrid motifs (two), and unique domains (three) are interspersed throughout the molecule[3-7]. Fibrillin 1 contains a proline-rich region close to the N-terminus that is replaced by a glycine-rich region in Fibrillin 2. The fibrillins are found throughout the connective tissue as integral components of extended fibrils.
Cellular Localization: Extracellular microfibrils.
Positive Control: Normal skin fibroblasts.
Applications:
Suitable for use in Immunofluorescence, Western Blot and Immunohistochemistry (Fr). Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
