  • Biologics production cell lines specifically made to ensure the highest yield and quality of products, and suitable for GMP manufacturing. See LakePharma’s CHO-GSNTM platform.

In addition to cell line development services, LakePharma provides scale-up bioproduction using stable cell lines.

Please view links above or contact inquiries@lakepharma.com for more information.

Bioassays

LakePharma provides a wide range of bioassays to support and monitor the activities of proteins and antibodies.

Bioassay services include functional measurement of ADCC and CDC activity and kinetic measurement of the interactions between ligands and receptors, including antigens and antibodies. Other services offered include quantification of contaminants, such as endotoxin and mycoplasma. 

Furthermore, quantification of target proteins and antibodies in plasma samples can be reliably determined using ELISA. When not commercially available, ELISAs can be custom developed. 

Finally, custom reporter gene assays, including luciferase, GFP, and beta-galactosidase, can be established to enable a multitude of applications, including the assessment of signal transduction pathways.

Please contact inquiries@lakepharma.com for more information. 

Bioanalytical

LakePharma offers a full line of protein analytical services. Latest advances in liquid chromatography and mass spectrometry techniques enable LakePharma to perform high resolution characterization of protein samples at a reasonable cost for all researchers. 

LakePharma's protein analytical services can identify a protein by molecular weight, sequence confirm the primary structure of a protein and detect post translational modifications, characterize a protein by aggregation, thermostability, size, charge, and pI, measure a protein's purity/impurity, determine the amino acid sequences of a purified protein sample or discover the amino acid sequence of an antibody, compare one protein or antibody sample to a second sample or biosimilar molecule, and more.

While the services and details are listed on the left, clients are encouraged to discuss their specific needs with LakePharma. Please contact inquiries@lakepharma.com for more information.

Antibody Production

LakePharma has extensive experience with constructing and producing antibodies in our mammalian platforms. Antibody variable region genes (VH and VL) from a given antibody can be reformatted to encode a different constant region and other antibody-like molecules including Fab, scFv, and bispecific molecules. Multiple species and isotypes are available, with the option of synthesizing the constant region of choice.

These expression constructs can be expressed in HEK293 and CHO cells followed by protein purification, and rapidly produced at scales ranging from milligram to gram quantities. We also offer high throughput 96-block antibody productions to fit your antibody screening needs.

New - Intact Mass Spec Analysis for All Recombinant Antibody Productions

High resolution mass spectrometers have achieved significant resolving power for large molecules. At LakePharma we apply this unparalleled analytical capability to all recombinant antibodies we produce for our clients to enhance the quality standard, for peace of mind.

Antibodies are treated with PNGase F to remove N-glycans and reduced with DTT prior to intact mass analysis. The resulting spectra not only provide the accurate molecular weights of the antibody sample, but can also identify common modifications such as N-terminal pyroglutamate formation or C-terminal cleavage.

The spectra are included in our Certificates of Analysis. This QC step does not apply to non-standard antibodies such as scFv, bispecifics, antibody fusion proteins, antibody-drug conjugates, and antibodies with engineered sequences and PTM sites, etc.
