The SERVAGel™ Neutral pH 7.4 Gradient has all advantages of the SERVAGel™ Neutral pH 7.4 (cat. no. 43222) but shows even better resolution performance for proteins of low molecular weight (from 5 KDa up to approx. 100 KDa), separation range is from 5 kda up to 200 kDa. To improve resolution and sharpness of protein bands gels should be run using SERVA Tris-Tricine/SDS running buffer (cat. no. 42552), samples should be dissolved in Tris-Tricine/SDS sample buffer (cat. no. 42551).
