Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Possible cell adhesion receptor. It possesses an intrinsic protein tyrosine phosphatase activity (PTPase) and dephosphorylates EPHA2 regulating its activity.; The first PTPase domain has enzymatic activity, while the second one seems to affect the substrate specificity of the first one.
Gene References into Functions
  1. transferred nuclear Overhauser effects (trNOEs) have been employed in the docking program HADDOCK to generate models for the LAR-fondaparinux complex. These models are further analyzed by postprocessing energetic analysis to identify key binding interactions. PMID: 29570275
  2. PTPRF may have value as a predictive marker to identify which patients can obtain the greatest benefit from erlotinib in the post-first-line setting. PMID: 26291013
  3. Homozygous truncating PTPRF mutation causes athelia. PMID: 24781087
  4. PTPRF is down-regulated in hepatocellular carcinoma-facilitated tumor development. PMID: 24470239
  5. Interaction between the tripartite NGL-1, netrin-G1 and LAR adhesion complex promotes development of excitatory synapses. PMID: 23986473
  6. LAR functions as a negative regulator of adipogenesis. PMID: 19910497
  7. regulation of expression by cell density through functional E-cadherin complexes PMID: 12095414
  8. LAR PTPase domains play distinct functional roles in phosphorylation and dephosphorylation PMID: 12496362
  9. LAR as a crucial regulator of the sensitivity of two key insulin signalling pathways to insulin PMID: 15896785
  10. Results identify a protein tyrosine phosphatase as a potential substrate of TACE and describe proteolytic processing of PTP-LAR as a means of regulating phosphatase activity downstream and thus under the control of EGFR-mediated signaling pathways. PMID: 16478662
  11. Regulated degradation of liprinalpha1 is important for proper LAR receptor distribution, and could provide a mechanism for localized control of dendrite and synapse morphogenesis by activity and CaMKII. PMID: 17419996
  12. LAR and Src are identified as Death-associated protein kinase (DAPK) regulators through their reciprocal modification of DAPK Y491/492 residues and establishes a functional link of this DAPK-regulatory circuit to tumor progression. PMID: 17803936
