      Restriction digests of the clone give the following sizes (kb): BamHI--4.4, 3.4; BglII--6.4, 1.4; EcoRI--7.8; EcoRV--7.8; PstI--7.8. This fragment originates 1.25 kb 5' to a BglII site just 5' to the J(H) sequences. Subcloned from Ch28-6. Enzymes(s) not detecting polymorphism: SstI, EcoRV, EcoRI, HaeIII, PvuII, PstI, TaqI, NdeII.  |
