SANTA CRUZ BIOTECHNOLOGY, INC. TMEM50A shRNA (m) Lentiviral Particles: sc-154474-V

BACKGROUND PRODUCT TMEM50A (transmembrane 50A), also known as small membrane pro- TMEM50A shRNA (m) Lentiviral Particles is a pool of concentrated, trans- tein 1, is a 157 amino acid protein encoded by a mapping to human duction-ready viral particles containing 3 target-specific constructs that 1. is the largest human chromosome spanning encode 19-25 nt (plus hairpin) shRNA designed to knock down gene expres- about 260 million base pairs and making up 8% of the .

Each vial contains 200 µl frozen stock containing 1.0 x 106 infectious are about 3,000 on chromosome 1, and considering the great number units of virus (IFU) in Dulbecco’s Modified Eagle’s Medium with 25 mM of genes there are also a large number of diseases associated with chromo- HEPES pH 7.3.

Notably, the rare aging disease Hutchinson-Gilford progeria is asso- siRNA (m): sc-154474 and TMEM50A shRNA Plasmid (m): sc-154474-SH as ciated with the LMNA gene which encodes Lamin A. When defective, the alternate gene silencing products. LMNA gene product can build up in the nucleus and cause characteristic nuclear blebs. The mechanism of rapidly enhanced aging is unclear and is APPLICATIONS a topic of continuing exploration.

Stickler syndrome, Parkinsons, Gaucher disease and Usher syndrome are also associated with chromosome 1. A breakpoint has been identified in 1q SUPPORT REAGENTS which disrupts the DISC1 gene and is linked to schizophrenia. Aberrations in chromosome 1 are found in a variety of cancers including head and neck Control shRNA Lentiviral Particles: sc-108080. Available as 200 µl frozen 6 cancer, malignant melanoma and multiple myeloma. viral stock containing 1.0 x 10 infectious units of virus (IFU); contains an shRNA construct encoding a scrambled sequence that will not lead to the REFERENCES specific degradation of any known cellular mRNA. 1.
