Recombination Activation Genes (Rag) encode enzymes that play an important role in the rearrangement and recombination of the genes of immunoglobulin and T cell receptor molecules during the process of V(D)J recombination. Rag1 knockout rats lack mature B and T lymphocytes. Rag1 Knockout Rat Characteristics: 29 bp deletion within Exon 2 on chromosome 3 Homozygous Rag1 knockout rats display loss of RAG1 protein via Wester…
This fiber glass is made from fine glass fibers with diameters controlled to approximately 0.008mm. This makes the glass pliable and easy to use. Manufactured from No. 9989 glass, this fiber glass contains minimal heavy metals and is suitable for use as a filtering medium. It is supplied in the form of roving approximately 2 inches in diameter by 22 ft. long and packaged in 0.23 kg (½ lb.) bags. This product is only sold in a…
These flat, clear PYREX® dish bottoms will withstand repeated sterilization (wet or dry). Approximate dish bottom diameter and height is 95x12mm. The edges are beaded to provide greater mechanical strength. The bead also provides a means to equally space the side walls of the bottom and cover, thereby reducing the capillary action of the condensed moisture on the sides. They are not affected chemically or thermally by any of t…
