Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Product Notices

This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
Source of all serum proteins is from USDA inspected abattoirs located in the United States.
Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Antibody Details

1H7

The 1H7 monoclonal antibody specifically binds to the α subunit of the human insulin-like growth factor-I (IGF-I) receptor that is also known as CD221. CD221 is a receptor tyrosine kinase that has high affinity for IGF-1 and low affinity for insulin and IGF-2. CD221 is synthesized as a 180 kDa precursor molecule that is processed into two subunits, a 135 kDa α subunit which is disulfide-linked to a 90 kDa β subunit. The mature IGF-IR complex is comprised of two extracellular α subunits and two transmembrane β subunits that each possesses a tyrosine kinase domain. When bound by ligand, the IGF-1 receptor autophosphorylates multiple tyrosine sites in its β chains and phosphorylates other signaling molecules that regulate cell growth, development, and neoplastic transformation. CD221 is structurally and functionally similar to the insulin receptor (aka, CD220) and is expressed on a variety of human hematopoietic and non-hematopoietic cells. The 1H7 antibody does not crossreact with the human insulin receptor and can block IGF-I- or IGF-II-stimulated cell growth.

Format Details

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
