Carrier Free

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: LRRTM1

Human LRRTM1 (leucine-rich repeat transmembrane neuronal 1) is a 58 - 59 kDa (predicted) type I transmembrane protein, that belongs to the LRRTM family of proteins within the leucine-rich repeat (LRR) superfamily (1). It is synthesized as a precursor with a 34 amino acid (aa) signal sequence, a 393 aa luminal region, a 21 aa transmembrane region, and a 74 aa cytoplasmic region. The luminal portion of LRRTM1 contains three N-linked glycosylation sites and 10 LRRs flanked by cysteine-rich domains (1). The cytoplasmic region contains several tyrosine, serine, and threonine residues that have potential to be phosphorylated and thus to be involved in signal transduction (1). The C-terminal also contains a conserved glutamic acid-cysteine-glutamic acid-valine sequence for potential interaction with PDZ proteins (1 - 2). Mature human LRRTM1 is 97% aa identical to mouse LRRTM1. LRRTM1 is localized to the endoplasmic reticulum (3). In the mouse, beginning at 9dpc, low levels of LRRTM1 can be detected in the overlying ectoderm of the limb bud, dorsal otic vesicle, forebrain, midbrain, hindbrain, and in neural progenitors in the central neural tube (2). In the adult brain, it is highly expressed in the brain and salivary gland, and is detected at intermediate levels in the cerebellum, spinal chord, stomach, testis, and uterus (1). Functionally, LRRTM1 may be involved in the formation of the CNS and maintenance of CNS structure and function in the adult brain (1). In addition, LRRTM1 has been shown to be a maternally suppressed gene that is associated paternally with handedness and schizophrenia (3).
