Product Overview

Vitronectin XF™ is a defined, xeno-free cell attachment factor intended to support the growth and differentiation of human pluripotent stem cells (hPSCs) under serum-free, feeder-free conditions. Vitronectin XF™ is developed and manufactured by Nucleus Biologics, Inc. and distributed by Biological Industries USA, Inc. Vitronectin XF™ is a recombinant fusion protein that contains the entire human Vitronectin sequence (NCBI Reference Seq. NP_000629.3), and is to be used for coating of sterile, non-tissue culture-treated polystyrene dishes and plates. When used in combination with NutriStem® hPSC Medium, Vitronectin XF™ supports long-term growth and expansion of hPSCs in a completely defined, xeno-free culture system.

Vitronectin XF™ maintains pluripotency and normal karyotype throughout long-term culture of hPSCs in defined conditions without the need for a ROCK inhibitor when used in combination with defined, xeno-free NutriStem® hPSC media.

Vitronectin is a consistent and effective single-component alternative to Matrigel® and other undefined matrices, with simple plating protocols and enzyme-free passaging options.

Sample Data

Figure 1: Normal cell morphology. hiPS cells thawed directly into NutriStem® hPSC XF Medium on Vitronectin XFTM substrate in the absence of the ROCK inhibitor Y-27632. The images demonstrate that cells grown in these conditions assume normal pluripotent cell morphologies as they expand from the early (Day 1, left image) to the late (Day 7, right image) phases of growth after thawing and/or passaging. Images shown at 20X magnification.

Instructions for Use
  • This product contains 500 µg Vitronectin XF™ in 2 mL of solution, at a stock concentration of 250 µg/mL.
  • Further dilution to a working concentration of 10 ug/mL in DPBS with calcium and magnesium is recommended prior to plating for hPSC culture. Refer to the Instructions for Use for full directions on preparing plates.
  • Coating should be performed on the day of use, although plates coated with Vitronectin XF™ solution may be incubated overnight at 37°C in a humidified CO2 incubator (with care taken to not let plates dry).
  • Important – use only with non-tissue culture-treated polystyrene plasticware when performing all dilutions.
