| T1 |
0-135 |
Sentence |
denotes |

| T2 |
136-276 |
Sentence |
denotes |
Using an anti-GD1b monoclonal antibody, expression cloning of a cDNA for the beta1,3-galactosyltransferase gene (EC 2.4.1.62) was performed. |
| T3 |
277-437 |
Sentence |
denotes |
KF4C, mouse melanoma B16 transfected with polyoma T antigen gene, and GM2/GD2 synthase cDNA was used as a recipient cell line for the cDNA library transfection. |
| T4 |
438-578 |
Sentence |
denotes |
A cDNA clone of GD3 synthase, pD3T-31 was co-transfected with a cDNA library prepared from rat brain RNA using the pcDNAI expression vector. |
| T5 |
579-779 |
Sentence |
denotes |
The isolated cDNA clone pM1T-9 predicted a type II membrane protein with 4 amino acids of cytoplasmic domain, 21 amino acids of transmembrane region, and a large catalytic domain with 346 amino acids. |
| T6 |
780-931 |
Sentence |
denotes |
Introduction of the cDNA clone into a mouse melanoma line B16 previously transfected with a GM2/GD2 synthase gene resulted in the neo-synthesis of GM1. |
| T7 |
932-1051 |
Sentence |
denotes |
Co-transfection of the cell line with pM1T-9 and a GD3 synthase cDNA resulted in the expression of GD1b as well as GM1. |
| T8 |
1052-1222 |
Sentence |
denotes |
Moreover, introduction of pM1T-9 into L cell (lacking GM3 synthase), previously transfected with GM2/GD2 synthase gene, resulted in the definite expression of asialo-GM1. |
| T9 |
1223-1347 |
Sentence |
denotes |
