Lck Overexpression Lysate Summary

Description

Lck Transient Overexpression Lysate


Expression Host: HEK293T

Plasmid: RC219430

Accession#: NM_001042771

Protein Tag: C-MYC/DDK

You will receive 1 vial of lysate (100ug), 1 vial of empty vector negative control (100ug), and 1 vial of 2xSDS sample buffer (250ul). Each vial of cell lysate contains 100ug of total protein (at 1 mg/ml). The 2xSDS Sample Buffer consists of 4% SDS, 125mM Tris-HCl pH6.8, 10% Glycerol, 0.002% Bromophenol blue, 100mM DTT.
Gene
LCK

Applications/Dilutions

Dilutions
  • Western Blot
Application Notes
This product is intended for use as a positive control in Western Blot. Overexpression of the target protein was confirmed using an antibody to DDK (FLAG) epitope tag (NBP1-71705) present on the protein construct.

Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
Theoretical MW
57.8 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Notes

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

Background

The human T-cell or lymphocyte specific gene Lck/p56 is a member of the Src family of non-receptors tyrosine kinase. Mostly expressed in T cells, Lck has been shown to be critical for the normal development of T lymphocytes (1). Additionally, the N-terminal region of the tyrosine kinase Lck interacts with the cytoplasmic domains of CD4 and CD8 (2). Autophosphorylation at Tyr-394 appears to be required for maximum catalytic activity (3) but it can also be suppressed by phosphorylation of the carboxyl-terminal tyrosine Tyr-505 (4).

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Lysates are guaranteed for 6 months from date of receipt.

CD45 was detected in immersion fixed paraffin-embedded sections of mouse liver using Goat Anti-Mouse CD45 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF114) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to Kupffer cells.
