ASAM Protein, Rat, Recombinant (His Tag)

Product Specifications

Background

Adipocyte-specific adhesion molecule (ASAM), also known as ACAM and CLMP, is a type I transmembrane protein and a member of the CTX (cortical thymocyte marker in Xenopus) family within the immunoglobulin superfamily. ASAM protein is highly expressed in the small intestine and placenta, and is found at intermediate levels in the heart, skeletal muscle, colon, spleen, kidney, and lung, and appears in low levels in the liver and peripheral blood leukocytes as well. ASAM is a transmembrane component of tight junctions in epithelial cells that can mediate cell aggregation and regulate transepithelial resistance across polarized epithelial cells. In addition, its expression is strongly correlated with white adipose tissue (WAT) mass of human and rodents with obesity.

Overview

A DNA sequence encoding the rat ASAM (Q8K1G0) (Met1-Met232) was expressed, fused with a polyhistidine tag at the C-terminus.

Synonyms

ACAM Protein, Rat; Asam Protein, Rat; Ol16 Protein, Rat

Gene Name

CXADR-like membrane protein

UniProt

Q8K1G0

Expression System

HEK293 Cells

Tag

C-His

Endotoxin

< 1.0 EU per μg of the protein as determined by the LAL method.

Purity

> 85 % as determined by SDS-PAGE.

Activity

Measured by the ability of the immobilized protein to support the adhesion of MS-1 cells. When 5 x 10E4 cells/well are added to Recombinant Rat ASAM coated plates (12.5 μg/mL with 100 μL/well), 35-70% cells will adhere after 1 hour incubation at 37°C.

Form

Lyophilized

Buffer

Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

Molecular Weight

The recombinant rat ASAM comprises 226 amino acids and predicts a molecular mass of 25.6 kDa. The apparent molecular mass of the recombinant protein is approximately 37 kDa in SDS-PAGE under reducing conditions due to glycosylation.

Storage Conditions

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
