Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

LMAN1 (E2B6H) Rabbit mAb recognizes endogenous levels of total LMAN1 protein.Species Reactivity:
Human, Mouse, Rat
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu366 of human LMAN1 protein.
Mannose-binding lectin-1 (LMAN1, ERGIC-53) is a type I transmembrane lectin protein localized to the intermediate compartment between the endoplasmic reticulum and the Golgi body (ERGIC) (1). Interaction between the LMAN1 protein and MCFD2 forms an ERGIC cargo receptor that delivers proteins from the ER to the Golgi body (2,3). The LMAN1 protein contains an amino-terminal carbohydrate recognition domain (CRD) that binds target glycoproteins, a membrane proximal oligomerization domain required for cargo transport, a single transmembrane segment, and short cytoplasmic tail (3-5). LMAN1 functions as a cargo receptor responsible for transport of glycoproteins from the ER to ERGIC and Golgi body. Target proteins include coagulation factors V and VIII, cathepsin C, cathepsin Z, and α1-antitrypsin (6-8). Mutations in the corresponding LMAN1 gene can result in combined factors FV and FVIII deficiency, an autosomal recessive disorder characterized by spontaneous bleeding (9). Inactivating frameshift mutations in LMAN1 are found at high frequency in colorectal tumors with microsatellite instability and may contribute to tumorigenesis (10).
