Product description
Gibco™ GlycanTune™ B+ Total Feed (Cat.No.A29720) is an AGT™ dry‑format, total feeding supplement developed for use in fed‑batch
culture of multiple cell lines. The single‑part supplement can shift glycan profiles from mostly G0F to primarily G1F and G2F
glycans. GlycanTune™ B+ Total Feed is an animal‑origin free, chemically‑defined formulation that contains no proteins, hydrolysates,
or components of unknown composition. The product provides an easy‑to‑reconstitute, pH‑neutral solution that can be concentrated from
59.2 g/L (1X; recommended) up to 177.6 g/L (3X), thus allowing delivery of key nutrients in smaller volumes.

Guidelines for maximizing protein glycosylation
To maximize protein glycosylation, GlycanTune™ B+ Total Feed
can be added as a complete standalone feed every 1–3days
or as a continuous feed. To target glycosylation profiles, initiate
feeding with EcientFeed™ B+ AGT™ Supplement, then transition
to GlycanTune™ B+ Total Feed. (Both feeds can be added every
1–3 days or as continuous feeds.) The timing of the transition
to GlycanTune™ B+ Total Feed will determine the glycosylation
profile. We recommend testing at least three dierent transition
time points (early, middle, and late culture) to determine the
optimal transition point that will result in the desired glycan profile.
Total feed volume can range from 10–45% (1X) to 3–15% (3X)
of the starting culture volume, depending on the cell line and
process. For best results, we recommend that you initiate feeding
only after reaching mid‑ to late‑exponential phase.
For example feeding strategies, see “Feeding examples” on
page2.
Reconstitute GlycanTune™ B+ Total Feed
1. Measure 80% of the final volume of deionized or distilled
water at room temperature (15°C to 30°C).
2. Add GlycanTune™ B+ Total Feed to the water at 59.2g/L
(recommended), then mix for a minimum of 20 minutes
until completely dissolved. The solution will initially appear
cloudy, but will clear over time.
Note: Depending on your culture needs, GlycanTune™ B+
Total Feed can be concentrated up to 177.6g/L (see
Table1).

3. Using a calibrated vessel, dilute to the final volume with
deionized or distilled water. Mix for an additional 10 minutes.
4. Measure pH and osmolality. Confirm a final pH of 6.8–7.3
and final osmolality of 375–415mOsm/kg.
5. Sterilize immediately by membrane filtration
(positive‑pressure recommended).
Use the filtered solution immediately or store at 2°C to 8°C
protected from light for up to 30days.
