FITC-d assay work flow for (A) the standard protocol used with normal serum samples (serum pooled from all treatment groups is used as diluent in the standard curve and unknown samples are blanked to the pooled background of all treatments) and (B) the modified protocol for highly autofluorescent serum samples (per treatment background autofluorescence subtracted from each unknown serum sample . solvents to remove traces of low-molecular-weight substances. Dextran - Wikipedia TdB Labs offer blue dextran in a wide variety of molecular weights, ranging from 5 kDa to 2000 kDa. Improved Nasal Bioavailability of FITC-Dextran (Mw 4300) from ... All batches are checked for molecular weight, degree of substitution and loss on drying. Fluorescein isothiocyanate-dextran average mol wt 70,000, FITC:Glucose ... 5 depict the increase in FITC-dextran observed in the sample mother-liquor over time for two and six bilayer samples, respectively. Fluorophores. A, B: The correlation of the two methods was excellent (r=0.97); C: The area was 1.31±0.21mm 2 by CD31 immunofluorescence and 1.11±0.19 mm 2 by FITC-Dextran perfusion method. It is a good idea to aliquot the dextran solution to prevent repetitive freeze-thawing. Centrifuge to get rid of the foam. Fig. Oral administration of fluorescein isothiocyanate dextran (FITC-d) has been used as an indicator for intestinal permeability in poultry research for several years. Get medical attention. . Eyes: Wash thoroughly with water for 15 minutes. Molecular weight dependence on bioavailability of FITC-dextran after ... The FITC-dextran is easily dissolved into PBS, could I dissolve them, and prepare 1mg/ml stocking solution, store at -25℃. CAS Number: 60842-46-8 Fluorescein isothiocyanate (FITC)-dextrans are synthesised by coupling fluoresceinyl isothiocyanate (5-isomer) to selected dextran fractions. DEAE-dextran. Sonicate the FITC-dextran solutions in bath sonicator for 10 min to disrupt possible aggregates. Uptake of the solution was allowed to proceed for 5 minutes, after which the leaf was removed from the plant, the chip area was excised with a scalpel and the chip was removed. Repeat for all mice.
