Rac 2 (L-10): sc-23121
BACKGROUND
A large number of low molecular weight, GTP binding proteins of
the Ras superfamily have been identified (1). These proteins regulate
many fundamental processes in all eukaryotic cells such as growth,
vesicle traffic and cytoskeletal organization. GTPase-activating
proteins (GAPs) accelerate the intrinsic rate of GTP hydrolysis of
Ras-related proteins, resulting in downregulation of their active
form (2-6). Two proteins in this family, Rac 1 and Rac 2, are
92% identical and share GTP binding and GTP hydrolysis motifs
with other members of the Ras superfamily (7,8). Rac 1 is
expressed in a large number of different cell types. Rac 2 is
primarily expressed only in myeloid cells (8) and has been reported
to be a regulatory component of the human neutrophil NADPH
oxidase (9).
SOURCE
Rac 2 (L-10) is an affinity purified goat polyclonal antibody raised
against a peptide mapping near the carboxy terminus of Rac 2 of
human origin.
PRODUCT
Each vial contains 200 µg IgG in 1.0 ml PBS containing
0.1% sodium azide and 0.2% gelatin.
Blocking peptide is available for competition studies (sc-23121 P)
(100 µg peptide in 0.5 ml PBS with 0.1% sodium azide and
100 µg BSA).
SPECIFICITY
Rac 2 (L-10) is recommended for the detection of Rac 2 of mouse,
rat and human origin by Western blotting and immunohisto-
chemistry.
Recommended dilution range for Western blot analysis:
1:100–1:1000. Recommended starting dilution: 1:100.
STORAGE
Store at 4° C, do not freeze; stable for one year from the date of
shipment.
RESEARCH USE
For research use only, not for use in diagnostic procedures.
