Immunohistochemistry Services

Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

TCR Screening Services

Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

LSBio Assay Kits

Assay Kit Image
LSBio’s growing collection of Assay kits provide researchers with the tools necessary to monitor various biological processes in the course of their life science research, drug discovery & development, or environmental monitoring studies. Assay kits are available for monitoring cell proliferation, damage, and oxidative stress, cytotoxicity, apoptosis, metabolism, signaling pathways and signal transduction. Each kit includes all of the necessary reagents to conduct the assay, and a clear, detailed protocol. LSBio’s experienced technical staff is also available to address any questions researchers may have about each kit and how they may be used to generate optimal results.

Cell Viability Assay Kit - HepG2 Cells were cultured in 3D cell Culture BME Matrix for 21 days and spheroids were formed. Before dissociation, each spheroid was isolated from matrix and images were captured for sizing purposes (spheroid sizes i-iv, scale bar = 200 µm). Next, spheroids were dissociated, stained with Calcein AM, and measured following Viability Assay protocol (? RFU data are shown in bar graph).

Cell Viability Assay Kit - Lysosomal Staining in Jurkat cells. 1x106 Jurkat cells were treated with vehicle or Positive Control Reagent for 24 hours. After treatment, cells were incubated in 1 ml of Assay Buffer with 1X Lysosomal Staining for 10 minutes at 37°C, followed by stain with 1X Cell Death Marker according to the kit’s protocol. Cells treated with vehicle (left panel; basal level of lysosomal staining), or Positive Control Reagent (right panel; green fluorescence). Increased green fluorescence compared to the basal levels confirms accumulation of Lysosomal Stain inside activated lysosomes. Low levels of red fluorescence resulting from Cell Death Marker shows low levels of Lysosomal Stain toxicity.

Cell Viability Assay Kit - Analysis of Live/Dead HeLa Cells by Microscopy: HeLa cells were cultured overnight with (d-f) or without (a-c) comptothecin (5 µM), which induces apoptosis. Next day, cells were treated with Staining Solution, as described in the protocol. Light and fluorescence images of cells were taken using Nikon TiE microscope. Treatment with comptothecin caused increased apoptosis in cells, which is demonstrated by increased number of dead cells, as shown in f.

Cell Viability Assay Kit - Cell Viability Assay: Fibroblast cells were grown in DMEM supplemented with 10% FBS, harvested using trypsin and counted using Trypan blue and a hemocytometer. Cells were serially diluted in a clear cell culture plate and incubated for 30 min. with Calcein AM at 37°C. After incubation, cells were lysed using Cell Lysis Buffer for 10 min. at room temperature. Cell lysates were transferred into a 96-well white plate & fluorescence was measured. Inset graph is an expanded segment of the assay data at lower cell number per well.
